-General Concepts
-
-The panel on the left is called the layers panel.
-It determines which layers and sublayers (such as tracks and waypoints)
-are shown, and the order in which they are drawn. Layers list on the
-top of the layers panel are drawn last. You can change the order by
-drag and drop, or by selecting a layer and using the up and down
-buttons at the bottom of the layers panel.
-
+
-The main Viking area where the layers are draw is called the viewport.
+&appname; is under continual improvement: see the potential areas in the Roadmap / Wishlist:

-Layers
-TrackWaypoint Layer
+
+General Concepts
+Layers
-TrackWaypoint layers display GPS data (tracks and waypoints).
+Layers is concept one may know from powerful graphics editors such as Photoshop or GIMP.
+Instead of putting all the data on the same level, it is stacked (i.e. layered) with different data over one another.
+This can be useful for analysis and general handling of various sets of data.
-An easy way to create new waypoints is to copy a
-latitude/longitude coordinate pair, such as the one shown on most
-geocaches, and paste it into an active TrackWaypoint layer. Viking can
-automatically recognize several variations of the lat/lon format.
-By right-clicking tracks and waypoints in the layers panel, you can do
-many things with tracks and waypoints. You can easily find a specific
-track or waypoint by expanding the Tracks or Waypoints sublayers in the
-layers panel to show all tracks or waypoints, and typing the name of
-the track/waypoint.
+Unfortunately the downside of this complexity is remembering how differing layers of data can obscure other data.
-Layer Operations
-The layer has a context menu with several operations.
+The Map layers have Alpha Compositing,
+to create the appearance of partial transparency.
+By controlling this value one can see data below it in the layer heirarchy for interesting effects.
-Export
+
+Layers Panel
-The layer can be exported to a file GPX, GPSPoint or GPSMapper format.
+The panel on the left is called the layers panel.
+It determines which layers and sublayers (such as tracks and waypoints)
+are shown, and the order in which they are drawn. Layers on the
+top of the layers panel list are drawn last. You can change the order by
+drag and drop, or by selecting a layer and using the up and down
+buttons at the bottom of the layers panel.
+
+Viewport
-Note: only the entire layer can be exported, it is currently
-(SVN:897, v0.9.7) not possible to export an individual track. IMO an
-oversight.
+The main &appname; area where the layer data is drawn, is called the viewport.
-
-
+Statusbar
+This provides a readout of various information:
+
+The currently selected (mouse pointer) tool
+The number of items to process in the background - normally this the number in the map tile download queue
+The zoom factor
+The location of the mouse pointer (and potentially height information if DEM data is available)
+
+When creating a track/route, the statusbar also displays some information about the track/route.
+
+Statusbar
+
+
+
+
+This part of the statusbar displays:
+
+The total distance of the track/route (including currently edited segment).
+The bearing of the currently edited segment.
+The distance of the currently edited segment.
+
+
+For convenience, a zoom selector can be opened from the status bar. Simply left-click on the zoom factor.
+
+ The zoom selector available from status bar
+
+
+
+
-Track Properties
+
+Projections
-Show many useful statistics about a track, including a
-elevation-distance graph and a speed-time graph (if data is available).
-You can click these graphs to jump to the point in the track. You can
-also reverse a track, delete duplicates, and split a track from its
-component segments (discontinuous breaks in a track) into separate
-tracks.
+&appname; supports differents projections:
+
+
+UTM
+
+
+LatLon (also called EPSG:4326)
+
+
+Mercator (also called Spherical Mercator)
+
+
+
+
+Map Cache
-The following colors are used in the elevation-distance graph:
+&appname; stores downloaded map tiles to disk for a couple of reasons:
-
+
+Enables off line usage
+Reduces loading on the map tile provider
+
-Brown profile: elevation data in graph
+The &appname; automatic caching strategy is two fold:
-
+
-Yellow: no elevation data
+ If the age of the tile on disk is less than the specified tile age (see ),
+ it will not attempt to contact the server to get a new version of the tile.
-Green: elevation data from DEM
+ When the tile age has expired &appname; will attempt a refresh update, so that it provides the cached tile generation timestamp so the server can determine if a new tile image needs to be returned. Not all map types support this refresh method.
-
+
-Red: speed
+ You can override the caching scheme by using right-click on the Map on the layers panel and selecting Redownload All Onscreen Maps, or Ctrl+F5 for the top most map displayed. This will get the latest version held by the server.
-
-
-
-
-Track Operations
-Merge by time
-This operation repeatedly tries to merge the right-clicked track
-with tracks in the same TrackWaypoint layer. The tracks which are
-merged are those which have at least one trackpoint less than some
-threshold time away. This way, if you somehow end up with lots of small
-segments (say, caused by turning the GPS on and off) you can merge them
-easily into one track.
-
-
-Split by time
+
-This operation will split a single track into segments wherever the
-time interval between successive trackpoints is larger than some
-threshold. This is useful when processing raw NMEA GPS data, especially
-taken over a long time.
-
+ This can be useful if you contribute to OpenStreetMap and wish to see your modifications (of course give time for the server to have processed your changes - see I have made edits but they don't show up on the map)
+
+
-Apply DEM data
+
+Shortcut Keys
-If any DEM data is loaded, this will apply the DEM data to give the track elevation data.
+&appname; has several shortcut keys or key combinations for commands as listed in the main window along side the command.
-
-
-Extend track end
-Change the current tool to add track and add points to the end of the track.
+Some function keys follow standard GUI behaviour:
-
-
-Upload to OSM
+
+F1 Help (view this manual)
+F5 or Ctrl+R Refresh the maps on screen
+F10 Select the Menubar (in built behaviour)
+F11 Full Screen
+Ctrl+F5 or Ctrl+Shift+R Redownload the maps on screen
+
+
-Useful if you are an OpenStreetMap.org (OSM) contributor. Viking
-allowing you to import a track, edit it if you so wish to remove
-duplicate points, perhaps track points leading to your home, and then
-directly export the track to OSM
+Refresh attempts to get new maps only if the local tile cache time period has expired for any particular map tile.
+Redownload gets all on screen maps from the server, ignoring the local tile cache.
-
-
-View Google Directions
-Launch a web browser to see the Google directions page which
-yielded the route. Note: the record of the Google route is stored in
-the track's comment, so if the comment is changed (or the route was
-created by something other than the Magic Scissors tool) this will not
-work correctly.
+
+
+Other function keys control turn on/off visibility of various elements:
-
-
-
-
-Waypoint Operations
-Goto Geocache page
+
+F3 Toggle visibility of the Toolbar
+F4 Toggle visibility of the Menubar
+Shift+F5 Toggle visibility of the Scale indicator on the viewport
+F6 Toggle visibility of the Center Crosshairs on the viewport
+F7 Toggle showing selected items (e.g. tracks or waypoints) in the highlight colour in the viewport
+F9 Toggle visibility of the Layers Panel
+F12 Toggle visibility of the Statusbar
+
-If the waypoint's name is in Geocache form (GCXXXXX) you can launch a web browser to go to the Geocache page.
+Standard shortcuts are provided for normal GUI operations: such as creating new files, opening, saving and exitting.
+Then there are shortcuts specific to &appname; to switch projection modes, zoom in/out, create layers and switch the active tool mode.
+For these combinations see the menu entry themselves.

-GPSLayer
-GPSLayer is responsible for uploading and downloading GPS data
-from a GPS device. It also is responsible for realtime GPS tracking.
-Expand the GPSLayer in the layers panel to see the two TRWLayers it
-uses for uploading and downloading. To upload, download, or use
-realtime tracking, right-click the GPSLayer and click the appropiate
-menu item.
+Tracks vs Routes
+
+In theory a route is path you are planning to follow and a track of where you have actually been. The GPX specification splits these into two separate catergories, although tracks contain everything route may have.
-Download
-To download data from the GPS, right-click the GPSLayer and click Download from GPS.
+Q. When planning a route what difference does it make if it's a route or a track?
-
-
-Upload
-To upload data to the GPS, first populate the GPS Upload child
-layer of the GPS layer (either by creating waypoints/tracks in it, or
-copying and pasting or dragging waypoints/tracks from another layer).
-Then right-click the GPSLayer and click Upload to GPS.
+
+A. One difference is in how a GPS device navigates following the route or track.
+Or you may want to consider interoperability with other software.
+Otherwise it is probably best to use tracks as they are a superset of the route functionality.
-
-
-Realtime tracking
-You must set up gpsd correctly or use a GPSD server and put the
-correct information in the GPSLayer properties dialog. Then right-cilck
-the layer and select Start realtime tracking.
+
+For example on Garmin Etrex:
-
+
+
+Route following: Uses navigation mode with compass and estimated time to next point.
+If following on road it can calculate a route on fly.
+I (RN) always use this mode to follow pre planned routes.
+
+
+Track following: Uses a TracBack mode
+I (RN) never use this so I can't comment on how it actually compares to the route mode.
+
+
+
+There are often restrictions on the numbers of route points the GPS Device can handle - may be 250 or as little as 50.
+This generally not a problem for single day routes, but needs managing for multi-day events or for highly detailed routes.

+File Types and the Main Window
-
-Tools
-You can use the scroll wheel and the right-click to zoom and pan no matter what tool you are using.
+&appname; has it's own file type traditionally marked by the .vik file extension.
+This is a plain text file saving all information of the current window including the view location, zoom level, projection type and then all the layer information (aggregrates, maps, tracks, waypoints, etc...).
-Scroll: zoom in and out without changing center (also Ctrl+, Ctrl-)
+Besides it's own file type, &appname; can open (and save to via export methods) GPX and KML file types.
+
-Ctrl-scroll: pan north-south (also Ctrl-up, Ctrl-down)
+&appname; does not handle GPX 1.1 particularly well - it prefers GPX 1.0
+
-Shift-scroll: pan east-west (also Ctrl-left, Ctrl-right)
+By default &appname; opens a default blank window centered on the home location. This behaviour can be changed by the .
+Each window contains menus, a toolbar, a viewport, layers panel and a statusbar.
+Each section (apart from the viewport) can be hidden using the or from the
+ViewShow choices.
-Ctrl-shift-scroll: zoom in and out, keeping mouse over same location (like Google maps)
+One may consider each &appname; window to be a separate project - each with it's project Viking file.
+However generally one window is enough for most purposes!
-Middle-click: make the clicked point on the map the center
+Several operations apply at the window level as follows next.
+Also see for the operational modes that generally work in conjunction with a selected layer.
+
+New
-Middle-click and drag: pan
+Located on the FileNew menu and on the toolbar New.
-Zoom
-Zooms in and out on the clicked part of the map.
+This creates a new window with the default settings.
-
-Ruler
-Used to measure bearing distance between two point:Click on first
-point,click on second point - after few seconds the bearing distance
-between points will be displayed.
-
-
-TrackWaypoint Layer Tools
+Open
-You must have a TrackWaypoint Layer selected to use these.
+Located on the FileOpen menu and on the toolbar Open.
-New Waypoint
-
-
-New Track
-Right-click: undo one point
+This opens a file chooser dialog to select one (or more) files of the supported GPS data file types:
+
+Viking
+GPX
+KML
+
-Ctrl: snap to trackpoint
+GPX and KML files will be loaded into the existing &appname; view. A Viking file will be given a new window if the current window is already assigned.
+
-Shift: snap to waypoint
+&appname; handles more file types via the Acquire methods below.
-
+
-Edit Waypoint
+
+Save
-Click/drag: select/move a waypoint
+Located on the FileSave menu and on the toolbar Save.
-Ctrl: snap to trackpoint
+If the current opened file is Viking file, this save will simply update it.
+If it is a new file or the file loaded was an external type (i.e. GPX or KML), then this will ask for a new name to save as a Viking file.
+
+
+Save As
-Shift: snap to waypoint
+Located on the FileSave As menu only.
-Right-click on waypoint: opens a menu with waypoint actions (the
-same menu accessed by right-clicking the waypoint in the layers panel)
+
+This will ask for a new name to save as a Viking file (even it was already a Viking file).
-
-Edit Trackpoint
+
+Append
-Ctrl: snap to trackpoint
+Located on the FileAppend menu only.
-Shift: snap to waypoint
+Selecting a Viking file from this method will join the file contents to the current window (instead of creating a new one).
+GPX and KML files may also be appended, but this is exactly the same as the normal file open method.
-
-Show Picture
+
+Acquire
+
+
+Available on the FileAcquire menu and from the layer menu.
+
+
+If used from the File menu and a TrackWaypoint layer is not currently selected, these methods place the results in a new TrackWaypoint layer. When a TrackWaypoint layer is selected, then using the FileAcquire will put the results into the selected TrackWaypoint layer.
+
-Uses eog to open a picture shown as a picture waypoint.
+If used from the layer menu these methods place the results in that TrackWaypoint layer.

-Magic Scissors
-Creates a track using Google maps routing between two points.
-Requires internet connection. Click one point, then click another to
-create a track.
+
+From GPS
+
+FileAcquireFrom GPS
+Probably the easiest way of getting information from a GPS Device.
-Right-click: undo last routing
+Select the GPS Device communication settings and then hit OK.
+See the Getting Started section for more info about the settings.
+
-Ctrl: continue previous track
+Some GPS devices (such as the Garmin Nuvi 255) support a native file system and write information to a Current.gpx file or similar. You will have to browse the file system on the device and open it directly.
-
+
-
-Georef Map Layer Tools
+
+Import File With GPSBabel
-You must have a Georef Map Layer selected to use these tools.
+FileAcquireImport File With GPSBabel
-Georef zoom
-Changes the zoom level of the georeferenced map and changes the
-Viking zoom level accordingly. Useful if you are trying to match GPS
-data to a georeferenced map.
+
+Other formats can be imported that are supported by GPSBabel.
-
-
-Georef move
-Drag to move the georeferenced map.

-Many services are available only via a web browser (Google Maps, OpenStreetMap Potlach editor, etc.).
+FileAcquireFrom Geotagged Images
+Enables automatic creation of waypoints from geotagged images.
-Jumping from &app; to such service can become annoying.
+This menu opens a dialog to select such image files.
+If the image files have geotag information in them, then a layer with named waypoints positioned at the location of each image with a thumbnail of that image is created.
+
+
+
+From Wikipedia Waypoints
-Viking allows you to open such service directly at the position currently viewed in &app;.
+FileAcquireFrom Wikipedia Waypoints
-This feature is called External tools.
+This gets interesting points from Wikipedia for the specified view: either within the extent of layer bounds or within the current viewport boundary.
-
-
-Mini-Howto's
-Getting Started
+
+From Routing
-To quickly get started using Viking, follow these instructions.
+FileAcquireFrom Directions
-Go to an area of interest
-Viking's default location is a 0 latitude and longitude, so you need to pick a place that interests you.
+This gets a route from given directions.
+
+
+
+
+Print
-Method A
+Located on the FilePrint menu and on the toolbar Print.
-1. Use View - Go to to move to a coordinate of interest.
+Print uses what is displayed on the current map view for printing: i.e. what ever map, tracks and waypoints that are in view, including the
+cross hairs and the scale.
-Method B
+It uses a standard system print dialog using an image the size of the current viewport in pixel terms.
+On the Image Settings you can move the image around the page and scale the image up / or down.
-1. Use GPS Layer or File - Acquire - From GPS to load data
-directly from your GPS into Viking. Currently Garmin and Magellan are
-supported. (NOTE: You must have write permission to the port used.
-/dev/ttyS0 is the first serial port)
+
+
+Generate Image File
+
+Located on the FileGenerate Image File menu only.
-Method C
+Allows generation of larger (pixel) area images than the standard Print method above.
+From the generated image you can use the facilities of the Operating System to print the image
+or perform other actions.
-1. Get data from files in GPX format. For other formats (kml,
-ozi...), use a converter such as GPSBabel to convert the files to GPX
-format first.2. Open up viking and use File - Open or File - Append
-file to open the file.3. Expand Tracks or Waypoints. Right-click on the
-track or waypoint of interest and select Goto.
-Method D
+You should have previously downloaded the tile images for the chosen zoom level,
+otherwise the image produced will have missing sections.
+
-1. Use File - Append File to add your track and waypoint data to
-Viking. This has been tested with Geocaching.com's *.loc format,
-(others(?)).2. Expand Tracks or Waypoints. Right-click on the tack or
-point of interest and select Goto
-
+Using large areas takes some time to process and due to the method used it may run out of memory to complete the operation.
+Unfortunately under Windows systems it can not detect this failure and may crash the program.
+So the maximum size is dependent on the capabilities of your system.
+For instance the largest successful image generated on my (RN) Debian system is a pixel area of 20,000 x 20,000.
+
+
-Add a map layer
-
-1. Use Layers - New Map Layer, and choose a suitable cache directory
-where you would like to store your tracks and click OK. Zoom to a
-comfortable level (I suggest 4 mpp) by clicking the left and right
-mouse buttons on the gray area where your tracks are. Now from the menu
-choose Tools - Map Download, Click where you would like to download a
-map. Regardless of what tool you are using, the middle mouse button
-always pans.
+
+Generate Directory of Images
-(NOTE: You MUST have an open internet connection when you are downloading maps. If not, viking will likely hang.)
+Located on the FileGenerate Directory of Images menu only.
+
-1. You will notice the maps are being drawn on top of the tracks, which
-is probably not what you want. Look at the Layers Panel to the left.
-Notice how the layer named Map is ABOVE your TrackWaypoint layer that
-your GPS data is in. This means that it will be drawn last, or on top
-of the other layers. Select the Map layer from the list and click the
-down arrow button beneath the list. Your tracks will now be drawn over
-the map.
-
+This is only available in UTM mode.

+TrackWaypoint Layer
-Maplayers new map layer
+TrackWaypoint layers display GPS data (tracks, routes and waypoints).
-
-in the layer properties dialogue choose e.g. OpenStreetMap (Mapnik).
+One way to create new waypoints is to copy a
+latitude/longitude coordinate pair, such as the one shown on most
+geocaches, and paste it into an active TrackWaypoint layer. &appname; can
+automatically recognize several variations of the lat/lon format.
-For the moment, we keep the default 'Maps Directory' (the directory in
-which the maps will be stored and can be used for offline usage).
-
-Check Autodownload maps and keep the zoom level as 'Use Viking
-Zoom Level' (note however, that these settings will play an important
-role in the pre-fetch for offline usage discussed later).
-
-You'll see a map of Stuttgart. Using the mouse wheel, you can
-zoom in and out. The maps for the choosen resoltion will be downloaded
-automatically.
+By right-clicking on tracks, routes or waypoints in the , you can access many commands on them.
+You can easily find a specific track, route or waypoint by expanding the appropriate containing Tracks, Routes or Waypoints sublayer in the

+The sublayers also offer right click menu options.
+These are the same as those available at the TrackWaypoint level, but only those that relate to the sublayer type.
+
-Sometimes, a tile does not show up correctly (you might see only a
-black frame in the map window) because it got corrupted during
-transfer. IN order to correct this, you can delete the corresponding
-datafile in the cache. right-click the DEM layer properties
+By default routes are coloured red. Tracks are automatically assigned a spread of colours.
+
-The 'DEM Files' listing allows you to delete the specific tiles (alternatively do this from the command line).
+Most operations available on tracks are available on routes, except for functionality that relies on having timestamps - since routes by definition have no timing information. Thus for example, uploading a route to OpenStreetMap Traces is not available nor is Geotagging on a route.
+It is possible to convert between Tracks and Routes, although converting from a Track to a Route may involve a loss of information (hence you are required to confirm this operation before it happens).
+
+Layer Operations
-You can also alter the Min. and Max. elevation in this dialogue.
+The layer has a context menu with several operations.
+View Layer
+
+Version1.1+: This will automatically move the viewport and select the best zoom level to see the whole layer (i.e. all tracks, routes and waypoints).
+
-GPS Track with height profile
+
+View
+
+View All Tracks
-uncheck the DEM layer (the map show up again)layers new trackwaypoint layer
+Version1.1+: This will automatically move the viewport and select the best zoom level to see the all the tracks in the layer (ignoring positions of any routes or waypoints).
+
+
+View All Routes
-Check to have the new track layer above the map layer.expand trackwaypointlayer, select 'Tracks'in the tools menue choose 'begin track' (red cross)leftclick in the map window, enter a nameclick several times to generate a track (a right-click removes the last point)expand 'tracks' in the layer menue, your track should show up, select itright click your track, select 'apply DEM data'right click your track again, select 'properies'click the tab 'elevation distance' - enjoy the plot
+Version1.4+: This will automatically move the viewport and select the best zoom level to see the all the routes in the layer (ignoring positions of any tracks or waypoints).
+
+
+View All Waypoints
-In order to save this setting for later usageclick OK in the 'track properties' dialoguefile save ase, choose a name (you can open this 'view' later via file open ).
+Version1.1+: This will automatically move the viewport and select the best zoom level to see the all the waypoints in the layer (ignoring positions of any tracks or routes).
+
-Usecase: offline data for holiday
+
+Goto Center of Layer
-Suppose you want to have the map and DEM data offline for your holiday in Italy near Bologna. Start a new viking session.view goto location, enter Bolognalayers new map layer
+This will automatically move the viewport to see the whole layer (i.e. tracks, routes and waypoints). It does not adjust the zoom level.
+
+
+Goto Waypoint
-Choose e.g. OpenStreetMap (mapnik).
+This opens a dialog box to enter a name of waypoint to search for. If it is found the viewport is centred on it.
+
-adapt the 'maps directory' e.g. to /home/user/.viking-map-holiday/.
-This allows you to delete the map stuff after holiday without purging
-the rest of your maps.
+Note this search is not very clever and only finds exact matches.
+You are probably better off expanding the waypoint list and directly start typing, as mentioned above, which finds a match based on each letter typed.
+
+
+
+Export Layer
-check autodownload map
+The layer (all tracks, routes and waypoints) can be exported to a file GPX, GPSPoint, GPSMapper or Google's KML format.
-keep 'viking zoom level'zoom out to 1024/1024add a DEM layer as discussed abovedownload the DEM data

+
+Upload
+
+Upload to GPS
+
+This opens a dialog to select the GPS Device and port to which the layer information will be transferred.
+
+
+The types of GPS information (tracks, routes or waypoints) to be transferred can be selected.
+
+
+Tracks, Routes or Waypoints that are invisible will not be transferred.
+
+
+
+Upload To OSM
+
+This opens a dialog to upload all tracks and waypoints to OpenStreetMap traces.
+Useful if you are an OpenStreetMap contributor (you will need an OpenStreetMap account), these details can be stored in &appname;
+
+
+ &appname; allows you to edit a track, e.g. remove duplicate points, perhaps remove track points leading to your home and then upload it to OpenStreetMap.
+
+
+
+The password is transferred unencrypted in every request sent to the OpenStreetMap server. This is due to the use of OpenStreetMap's basic authentication method.
+
+Currently &appname; does not support the OAuth mechanism.

+Delete
+Offers deletion of various parts of a TrackWaypoint layer:
+Delete All Tracks
+Deletes all the tracks in this layer.
+
+Delete Tracks from Selection
+Opens a dialog with list of all the tracks from this layer to choose the ones to delete.
+
+Delete All Routes

+
+Filter
+Simplify All Tracks
+
+This opens dialog to request the number of points each track will be simplified using GPSBabel. The result is put into a new layer. The simplification method removes points considered to be in a 'near straight line', thus reducing the number of points and attempting to keep the most important turning points.
+
+
+Remove Duplicate Waypoints
+
+Remove Duplicate Waypoints - fairly self explainatory, with the results created in a new layer.
+
+
+
+However it only considers a precise position (waypoints only 1 metre away from each other are considered different) and also doesn't consider if the waypoints have different comments, symbols or images.
+
+
+
+
+
+Filter With <emphasis>Trackname</emphasis>
+
+This runs GPSBabel on the layer using information from a previously selected track (select via the track menu "Use With Filter" option) with the following command types:
+
+
+Waypoints Inside This
+Waypoints Outside This
+
+
+The result is generated in a new Track/Waypoint layer.

+Track and Route Operations
+
+Finish Track
+
+Selecting this option ends the creation of the individual track.
+
+
+
+This is only available when a track is being created by the tool.
+
+
+
+
+Goto
+
+This centers the viewport on the selected position on the track:
+
+
+Startpoint
+"Center" - the notional center from the bounds of the track
+Endpoint
+Version1.1+: Highest Altitude
+Version1.1+: Lowest Altitude
+Version1.1+: Maximum Speed (Not Available on Routes)
+
+
+
+View
+
+Version1.1+: This centers the viewport on the track and selects the best zoom level to see it.
+
+
+
+Combine
+Merge By Time
+
+This operation repeatedly tries to merge the right-clicked track
+with tracks in the same TrackWaypoint layer. The tracks which are
+merged are those which have at least one trackpoint less than some
+threshold time away. This way, if you somehow end up with lots of small
+segments (say, caused by turning the GPS on and off) you can merge them
+easily into one track.
+
+
+
+This is not available on routes as they have no timestamps.
+
+
+
+
+Merge With Other Tracks
+
+This opens a dialog listing the other tracks in the same TrackWaypoint layer, from which one can select the other tracks to merge with.
+
+
+
+Merge Segments
+
+Combines track segments. Effectively removing track segment markers to leave one segment for the whole track.
+
+
+
+Append Track or Route
+
+Enable joining of a single track to the end of the current track.
+This opens a dialog listing the other tracks in the same TrackWaypoint layer from which one can make the selection.
+
+
+
+
+Split
+Split By Time
+
+This operation will split a single track into segments wherever the
+time interval between successive trackpoints is larger than some
+threshold. This is useful when processing raw NMEA GPS data, especially
+taken over a long time.
+
+
+
+This is not available on routes as they have no timestamps.
+
+
+
+
+Split By Number of Points
+
+Version1.2+: This operation will split a single track into segments by the number of points specified.
+This can be useful with devices which may have limits on the number of points it supports.
+
+
+
+Split Segments
+
+Splits track segments into new tracks.
+
+
+
+This is not available on routes as they do not have route segments.
+
+
+
+
+Split at Trackpoint
+
+Splits the track at the currently selected trackpoint.
+
+
+The current track will finish at this trackpoint.
+A new track will start from a copy of this trackpoint.
+
+
+
+This is only enabled when a trackpoint is selected.
+
+
+
+
+
+Insert Points
+
+
+These options are only enabled when a trackpoint is selected.
+
+
+Insert Point Before Selected Point
+
+Inserts a track point halfway between the previous track point and the current track point.
+All track point properties are interpolated between the two points.
+
+
+Insert Point After Selected Point
+
+Inserts a track point halfway between the current track point and the next track point.
+All track point properties are interpolated between the two points.
+
+
+
+
+Delete Points
+Delete Selected Point
+
+Deletes the currently selected track point.
+
+
+
+This is only enabled when a trackpoint is selected.
+
+
+
+Delete Points With the Same Position
+
+Deletes subsequent points that have the same position (but have different timestamps).
+
+
+Delete Points With the Same Time
+
+Deletes subsequent points that have the same time stamp (but may have different positions).
+
+
+
+This is not available on routes as they have no timestamps.
+
+
+
+
+
+
+Transform
+
+These options alter the data of trackpoints of a track but not add or remove trackpoints.
+And don't seem to fit any other category :)
+
+Apply DEM data
+
+If any DEM data is loaded, this will apply the DEM data to give the track elevation data.
+Two ways of applying DEM data are offered:
+
+Keep. Retains the existing elevation data of trackpoints and only those missing an elevation value are set.
+Overwrite. Elevation data are set on all trackpoints even if they already elevation values.
+
+
+
+Smooth Missing Elevation data
+
+In various locations across the world, there are missing DEM values (AKA DEM Holes) from the SRTM data.
+This is particularly noticeable in mountainous areas.
+Two ways of applying elevation data to trackpoints that do not have elevation values are offered:
+
+Interpolated. Missing elevation data is interpolated between the previous and next known values.
+Flat. Elevation data is filled in from the last previously known value.
+
+
+
+
+Convert to Track or Route
+
+If this is a Route then it will convert it to a Track.
+
+
+If this is Track then convert it to a Route.
+
+
+
+Converting from a Track to a Route may involve a loss of information, in particular timestamp values (hence you are required to confirm this operation before it happens).
+
+
+
+
+Anonymize Times
+
+Timestamp information of a track can be shifted to be all offset from 1901-01-01.
+
+
+Thus the timestamps themselves will no longer reveal exactly when a track was taken.
+However the relative difference between the timestamps is kept thus one is still able to calculate some properties such as speeds along the track.
+
+
+
+This is not available for routes, as they have no timestamps.
+
+
+
+
+
+Export Track as GPX
+
+Version1.1+: This allows exporting the track as a GPX file by opening a file save dialog.
+
+
+
+Extend Track End
+
+Changes the current tool to add trackpoints to the end of the track.
+
+
+
+Extend Using Route Finder
+
+Enables the Route Finder tool. Thus on a subsequent left click in the viewport, a route is calculated from the end of track to that point using the default route service and applied to the track.
+
+
+
+Upload
+
+Upload to GPS
+
+Same as the layer Upload to GPS command, but only applies to the track.
+
+
+
+Upload to OSM
+
+Same as the layer Upload to OSM command, but only applies to the track.
+
+
+
+
+
+Use With Filter
+
+This selects the track to be used in the Filter With Trackname feature.
+
+
+
+This is not available on routes.
+
+
+
+
+Edit Trackpoint
+
+This opens the Trackpoint edit dialog. See .
+
+
+
+This is only enabled when a trackpoint is selected.
+
+
+
+
+Refine Route...
+
+This function allows to request a Routing Engine in order to refine a given route.
+By "refining" we mean computing all real intermediates points between some given major points.
+This could be useful to compute a trip giving only the wished important steps.
+
+
+
+This is only available on routes.
+
+
+
+
+View Google Directions
+
+This option is only available on a track created using the Route Finder tool.
+
+
+Launch a web browser to see the Google directions page which yielded the route.
+
+
+
+The record of the Google route is stored in the track's comment, so if the comment is changed (or the route was created by something other than the Route Finder tool) this will not work correctly.
+
+
+
+
+
+
+Waypoint Sublayer Options
+Repeats options available at the TrackWaypoint level, but only those for waypoints:
+
+New Waypoint. Same as the layer New Waypoint
+View All Waypoints. Same as the layer View All Waypoints
+Goto Waypoint. Same as the layer Goto Waypoint
+Delete All Waypoints. Same as the layer Delete All Waypoints
+Delete Waypoints from Selection. Same as the layer Delete Waypoints from Selection
+List Waypoints. Opens a new dialog with the list. As described in the Aggregrate layer
+
+
+
+Waypoint Properties
+
+
+This shows a dialog with detailed information for the waypoint. Many properties of the waypoint can changed here, such as the comment, the symbol used in drawing or the image (normally a photograph taken at this position) assiocated with it. When a waypoint has an image, a thumbnail of it is drawn in the viewport for the waypoint (in preference to the symbol).
+
+
+If the waypoint has an associated image, then the Geotag information may be updated, either with updating the file's modification timestamp or not.
+This can be useful when the waypoint has been moved.
+
+
+
+
+Waypoint Operations
+
+Goto
+
+This centers the viewport on the selected waypoint.
+
+
+
+Visit Webpage
+
+If the waypoint's comment (or description) starts with http: then this option is available and allows launching a web browser to go to the webpage.
+
+
+
+Visit Geocache Webpage
+
+If the waypoint's name is in Geocache form (GCXXXXX) then this option is available and allows launching a web browser to go to the Geocache page.
+
+
+
+New Waypoint
+
+Same as the layer New Waypoint.
+
+
+
+
+
+Version1.3+: Geotag Images
+
+This dialog allows geotagging images (normally taken with a digital camera) via interpolation against a specific track or all tracks in the TrackWaypoint layer - depending on how it is invoked.
+
+
+Images need to have an EXIF DATE_TIME_ORIGINAL (nearly always set by a camera). This timestamp is then used to find the location when the image(s) was taken by searching through the track(s) to find the nearest time - interpolating between points if necessary to set the location.
+
+
+
+Generally it is good policy to synchronize your camera's clock with your GPS clock before taking photographs. However the times can be adjusted afterwards (if necessary) to take into consideration clock differences.
+
+
+
+Various options allow control of how the geotagging process is performed:
+
+
+Images - Add the images used for geotagging
+Create Waypoints
+Overwrite Existing Waypoints
+Write EXIF
+Overwrite Existing GPS Information
+Interpolate Between Track Segments
+Image Time Offset - The number of seconds to ADD to the photos time to make it match the GPS data. Calculate this with (GPS - Photo). Can be negative or positive. Useful to adjust times when a camera's timestamp was incorrect.
+Image Timezone - The timezone that the used when the images were created. For example, if a camera is set to AWST or +8:00 hours. Enter +8:00 here so that the correct adjustment to the images' time can be made. GPS data is always in UTC.
+
+

+
+GPS Layer
+
+The GPS layer is responsible for uploading and downloading GPS data
+from a GPS device. It also is responsible for realtime GPS tracking.
+Expand the GPS layer in the layers panel to see the two layers it
+uses for uploading and downloading. To upload, download, or use
+realtime tracking, right-click the GPS layer and click the appropiate
+menu item.
+
+
+Download
+
+To download data from the GPS, right-click the GPS layer and click Download from GPS.
+
+
+
+Upload
+
+To upload data to the GPS, first populate the GPS Upload child
+layer of the GPS layer (either by creating waypoints/tracks/routes in it, or
+copying and pasting or dragging waypoints/tracks/routes from another layer).
+Then right-click the GPS layer and click Upload to GPS.
+
+
+
+Realtime Tracking
+
+You must set up gpsd correctly or use a GPSD server and put the
+correct information in the GPS layer properties dialog. Then right-click
+the layer and select Start Realtime Tracking.

+
+DEM (Digital Elevation Model) Layer
+
+This layer provides elevation data from the Shuttle Radar Topography Mission (SRTM)
+
+
+Elevation data can be useful in planning trips, as you many wish to avoid/minimise the hills encountered. [OSM Cyclemap is also useful this way too]
+
+
+To download the data use the DEM Download tool (shown on the toolbar), and then click on a area of the viewport. Once files have been downloaded they can then be loaded from disk via the DEM properties in future application runs.
+
+
+The current data server is: NASA STRM 2.1.
+
+
+ATM &appname; does not auto download DEM data. If you want to get lots of data blocks, you may wish to use some other program get such as curl or wget to download them for an area.
+
+
+
+Using many DEMs is CPU/memory intensive. Depending on your computer's capability, &appname; will be less responsive when about 50+ DEM blocks are loaded. It is probably unwise to attempt using 200+ blocks, so trying to use DEMs covering large countries/continents (USA, Australia etc...) is unlikely to work. In these conditions under Linux, &appname; may be automatically stopped by the "OOM Killer"
+
+
+
+
+
+
+Maps Layer
+
+This layer provides a single map resource, you may have multiple map layers but only top one (if enabled) will be visible.
+You will need an open internet connection when you are downloading maps, but once downloaded they are available from the hard disk cache. When map are avaliable from the disk cache it is much faster and can be used offline.
+
+
+Some maps are continually improving over time (e.g. OpenStreetMap) and so in order to not to have to (re)download the data all the time &appname; employs a timeout method - Tile Age to determine whether to access the server. However a forced refresh for the current view can be made via the Reload All Onscreen Maps option.
+
+
+Inbuilt maps include various Terraserver (Primarily USA coverage) and OpenStreetMap (OSM) ones and more:
+
+
+Bing Bird's Eye (Aerial) Maps (&appname; Version1.2+)
+Terraserver Topos
+Terraserver Aerials
+Terraserver Urban Areas
+OpenStreetMap (Mapquest) - This is the default (&appname; Version1.3+)
+OpenStreetMap (Mapnik)
+OpenStreetMap (Cycle)
+OpenStreetMap (Transport) (&appname; Version1.3+)
+NASA BlueMarble
+SpotMap (&appname; Version1.1+)
+
+
+
+&appname; can be configured to handle additional maps. See for further detail.
+
+
+Layer Operations
+Download Missing Onscreen Maps
+
+This requests map tiles for areas of the viewport that do not currently have one.
+

+
+Download New Onscreen Maps
+
+This requests map tiles only if the maps are older than the Tile Age preference.
+
+
+
+Reload All Onscreen Maps
+
+Force a refresh of all visible map tiles.
+

+Download Maps in Zoom Levels
+
+This opens a dialog to enable requesting the download of maps for the region in the viewport over a specified number of zoom levels.
+The download method type can be specified to help limit the number of requests.
+
+
+
+There are some inbuilt limits to prevent downloading large amounts of map tiles.

+Aggregate Layer
+
+This layer is a container layer to hold other layers. There is always an initial and controlling Top Layer that can not be removed or renamed.
+
+
+This layer type is useful for grouping other layers, especially layers, in whatever categories are relevant to you: such as by activity, location or date.
+Here are some suggestions:
+
+Hiking
+Mountain Biking
+Road Cycling
+Car Trips
+Sailing
+Holidays
+UK Points of Interest
+USA Points of Interest
+etc...
+
+
+
+Thus one can have a list of all your tracks, but groups can be shown or not using the relevant layers visibility checkbox.
+
+
+Layer Operations
+
+The following are available on Aggregate Layers:
+
+
+
+New Layer
+
+Add a new layer of the selected type.
+
+
+
+Sort
+
+The list within the treeview can be sorted.
+
+
+Currently alphabetical (A to Z or Z to A) sorts are available, since only the name can be seen in the treeview.
+
+
+
+Track List
+
+Selecting this opens a dialog listing all the tracks in a table along side statistics such as track length and maximum speed.

+Auto Location - Use the web service hostip.info to attempt to determine your location via IP lookup
+
+
+Startup File
+Loads this specified file when the Startup method is set to Specified File
+
+Check For New Version
+Periodically (no more than once every 14 days), check to see if there is a new version of &appname; available.
+
+
+
+
+
+
+Howto's
+Getting Started
+
+&appname; from version 1.5 has several features to ease the start up process.
+On the very first run, you will be asked if you want to enable these features which make use of an Internet connection.
+If you select no or you have upgraded from an earlier version you can choose to enable any of the startup options via the .
+
+
+Some other general use cases for using &appname;, are as follows:
+
+Go to an area of interest
+
+&appname;'s default location is a Manhatten, New York, USA, so you may need to pick another place that interests you - such as where you live.
+
+
+Method A
+
+
+ Use the online location address/place search.
+
+
+ Use the Go to Location toolbar button or from the menus
+ ViewGo to Location.
+ You can change the search location provider if desired.
+ Enter the name of place you wish to go to (you may need to specify the country to refine the search).
+ Also you can enter a post code or a ZIP code instead.
+
+
+ You will need an internet connection for this search to work
+
+
+
+
+Method B
+
+
+ If you know the coordinates of where you want to view:
+
+
+Use View and select from either Go to Lat/Lon or Go to UTM and then enter in the specific coordinates.
+
+
+
+Method C
+
+Use the GPS Layer or FileAcquireFrom GPS
+to load data directly from your GPS into &appname;.
+
+You can specify the types of data to acquire: Tracks, Routes and/or Waypoints.
+
+
+You must have write permission to the port used. For Unix like OS:
+
+ /dev/ttyS0 is the first serial port
+ /dev/ttyUSB0 is the first USB port
+ usb: is any USB port
+
+Depending on your distribution only one of the USB port types may work
+For Windows:
+
+ com1: is the first serial port
+ usb: is any USB port
+
+
+
+ The GPS devices supported are those supported by GPSBabel.
+ Garmin and Magellan GPS devices supported by all versions, later versions of GPSBabel support more devices such as DeLorme and Navilink.
+
+
+
+
+Method D
+
+
+Get data from files in GPX or KML format, which can be opened directly.
+Use FileOpen
+
+
+Other formats can be imported that are supported by GPSBabel.
+FileAcquireImport File With GPSBabel...
+
+
+
+The viewport will be automatically moved and resized to view the contents of the file.
+
+
+
+
+
+Add a Map Layer
+
+Use LayersNew Map Layer, and choose a suitable cache directory
+where you would like to store your tracks and click OK. Zoom to a
+comfortable level (I suggest 4 mpp) by clicking the left and right
+mouse buttons on the gray area where your tracks are. Now from the menu
+choose the Tool. Click where you would like to download a
+map. Regardless of what tool you are using, the middle mouse button
+always pans.
+
+
+You need an open internet connection when you are downloading maps.
+
+
+
+If you can no longer see your tracks or waypoints and only the map,
+it is because the layer named Map is ABOVE your TrackWaypoint layer that your GPS data is in.
+This means that it will be drawn last and on top of the other .
+Look at the to the left which shows this order.
+Select the Map layer from the list and click the down arrow button beneath the list until the Map layer is below the TrackWaypoint layer.
+Your tracks will now be drawn over the map.
+
+
+
+Set Your Home Location
+
+ You can save the current center position of the viewport as the default location AKA the Home Location by
+ EditSet the Default Location.
+
+
+ Then at any time you can return to this place by clicking on the Home icon on the toolbar.
+
+
+ You can also set the default location via specifing the exact latitude and longitude in the .
+
+
+
+
+From 1st startup to GPS track (including offline maps)
+
+The first you'll see is an empty map, because &appname; in its default configuration will download maps only on demand.
+Before fetching unneeded data, one can position to a location of interest, e.g. Stuttgart: ViewGo to Location, enter Stuttgart.

+
+
+OpenStreetMap project
+
+OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world.
+One of sources of data for this project is GPS tracks.
+&appname; supports this project via the GPS Traces methods, both uploading and downloading such data.
+
+
+Also see for further detail.
+
+Uploading data to OpenStreetMap
+
+It is possible to upload data directly from &appname; to OpenStreetMap.
+
+
+Upload a layer
+
+One solution is to upload whole a layer. To do this,
+simply select the layer and right click on it. Then, select Upload to
+OSM.
+
+
+
+Upload a single track
+Another solution is to upload an individual track. Simply select the track and right click on it.
+Then select Upload to OSM.
+
+
+
+Fill in the form
+In both cases, &appname; will retain some information.
+The email field is the email you used to subscribed into OpenStreetMap.
+The password field is the password you used with this account.
+The filename is the name you want your upload has on the server. This information is displayed by the osm server.
The description is some descriptive information.
+The tags field is a white separated list of tags.
+
+
+
+
+Downloading Traces from OpenStreetMap
+
+It is possible to download GPS traces directly from OpenStreetMap into &appname;.
+This feature can be really useful for checking existing data before uploading new ones.
+
+
+Download all visible tracks
+One solution is to select
+
+File
+Acquire
+OSM traces...
+.
+Each request can get up to 5,000 points.
+The dialog box allows setting which group of 5,000 points to get. These groups are known as Page Numbers which start at 0.
+Increasing the page number parameter allows one to request the subsequent sets of point groups.
+
+
+
+Downloading Your Own Traces from OpenStreetMap
+
+It is possible to download any of your personal GPS traces previously uploaded to OpenStreetMap into &appname;.
-The tags field is a white separated list of tag.
+You will need to provide your OSM username and password to get the list of your OSM Traces.
+From this list you can select which traces to retrieve.
+This list can be sorted on each column so that it easier to find an individual trace or select a group of traces by similar properties.
+
+
+
+Geotagging
+
+ This assumes you already have a layer enabled for ease of use (if not see above to get one).
+
+Manual Positioning
+
+ This is useful for instances when you already know exactly where the image was taken (no need for tracklog).
+ Or maybe you want to adjust an automatically generated waypoint for the position of the subject of the image rather than the location that the photograph is taken from.
+ ATM this process only works on an individual image, so it will be tedious for handling lots of images.
+
+
+ First create a layer or use an existing one; and select it in the .
+ NB Make sure this layer is above the map layer in the Layers Panel list.
+ Create a new waypoint (or move an existing one) to exact location desired:
+
+ Select the tool, then left click on the map at the location desired, choosing an image to associate with it in the new waypoint dialog
+ Select the tool, then left click on waypoint to be moved. Left click again and drag the waypoint to the location desired
+
+ Then using the Select tool left click on waypoint to select it, then right click to access the Waypoint properties menu, then choose
+ Update Geotag on ImageUpdate
+
+
+ The Update Geotag on Image options are only available when a waypoint has an image associated with it.
+
-Geocoded Photo
+
+Automatic Positioning Against a Tracklog
+
+ First you will need a tracklog with timestamps in it. Either load one from a previously saved file or freshly acquired from a GPS device -
+ see Getting Started.
+ It helps if this is the track that was recorded at the time you took some photographs!
+
+
+ Select the track either from the layers panel on the left or via the viewport using the tool.
+ Then right click on it and chose the Geotag Images... leading you to the Dialog.
+
-HOWTO GEOCODE YOUR PHOTOS AND SEE THEM IN VIKING
+ Load some images that where taken around the time the track log was recorded. Confirm the other options in the dialog - normally the defaults should be alright and select OK.
+ If things are succesful, new waypoints with thumbnail images of the photographs will appear.
+ You should probably check they are really in the right place as often the timestamp of the camera may not be aligned to the GPS correctly leading to inferring incorrect locations.
-1) Synchronize your camera's clock with your GPS clock. If your
-camera's clock doesn't have a seconds value you can change, you might
-try setting the minute value just when the minute changes.
+Option: Overwrite Waypoints
+
+ This is particularly useful when one finds an attempt at geotagging gives wrong locations, often due to time offset issues.
+ Simply try again with a new time offset (often 1 hour adjustments due to Daylight Savings or Summer Time times) and the old waypoints will be updated (instead of creating new ones).
+
-2) Activate the track log on your GPS.
+ If you have multiple tracks in a TrackWaypoint layer, then invoking the Geotag Images... action on the layer
+ will search all the tracks to find location matches.
-3) Get outside and take some pictures with your camera while
-making sure your GPS has reception. If you forgot to turn your GPS on
-or forgot to bring it when you took a picture but you know where you
-took the picture, you can make a waypoint with a name of the format
-YYMMDDhhmm, representing the time the picture was taken, to record
-where you were at that time.
+
+
+
+GPS Real Time Location (Not <trademark>Windows</trademark>)
+
+ &appname; relies on gpsd to provide the current location from a real time feed from a GPS device.
+ Unfortunately gpsd is not available on Windows,
+ so currently this functionality is disabled in Windows builds of &appname;
-4) Get home and download your pictures and GPS data. You can
-download the GPS data several ways. The first is using gpspoint to
-download from a Garmin GPS: gpspoint -p /dev/ttyS0 -dw -dt -of 2004-04-02-trip1
+
+ This assumes you already have a layer enabled for ease of use (if not see above to get one).
-Where /dev/ttyS0 is the serial port the GPS is connected to. If you
-don't have a Garmin GPS, or if you don't feel like install gpspoint,
-you can use my version of gpsbabel with support for gpspoint files. You
-can use gpsbabel to either translate the GPS data from a format you
-already have the data in or download it directly from your GPS
-reciever. A typical command line would something like this:gpsbabel -i garmin -f /dev/ttyS0 -o gpspoint -F 2004-04-02-trip1
+ Turn on the GPS Device, ensure it has figured out it's location and plug it in to your computer.
+Set Up GPS Layer
-5) Launch GPSPhoto.
+ You will need a layer. One can be added via LayersAdd GPS Layer.
-6) You must now bring your photos into GPSPhoto. Either drag them (or
-the directory containing them) from your favorite file manager to the
-list on the left of the GPSPhoto window, or use the buttons below the
-list to find them.
+ Adjust the Realtime Tracking Mode settings to interface with gpsd as necessary. Normally the defaults should suffice.
-7) Do the same for your GPS data file(s), dragging them to the list on the right of the GPSPhoto Window.
+ Current Linux distributions should run gpsd automatically when a GPS Device is plugged in. Otherwise you may have to run gpsd manually.
-8) Click the Execute button, and choose a location to save the
-gpspoint file containing the waypoints for your photos. Then click OK
-to write the waypoints to this file.
+
+ Then right-click the layer and select Start Realtime Tracking.
+ Hopefully the viewport should jump to the GPS location.
-9) Open Viking and open both your original GPS data file and your image waypoint file just created.
+ Troubleshooting checklist:
+
+Confirm gpsd is running.
+Confirm on the GPS device it has a location.
+Confirm the Realtime Tracking Mode settings.
+
+
+
+What to Do if &appname; Does Not Seem to Work
+
+In order to get some information about what &appname; is doing, start it in verbose debug mode via the command line:
+viking -dV
+
+
+For instance you can check the correct URLs &appname; is using in requesting remote data for DEMs or map tiles in the verbose debug output.
+E.g. Something like this for DEMs:

+
+ Extending Viking
+
+ Currently, &app; has some extention points based on configuration files. The file format is heavily inspired by the GtkBuilder file format: you specify the class of the GObject to build and set its properties. Technically, it is a XML file containing a "objects" root element. Inside this element, you set a collection of "object".
+ Here is an example:
+
+
+ ...
+
+]]>
+
+
+ You can find more examples in the documentation part of the distribution.
+
+ Map Source
+ It is possible to add new map's sources. The file is ~/.viking/maps.xml for UNIX like systems and C:\Documents and Settings\username\.viking\maps.xml on Windows XP.
+ An example of the file is in the distribution doc/examples/maps.xml. Further examples and values are online in the Maps Wiki
+
+ The VikSlippyMapSource allows to declare any map's source working like OpenStreetMap. It supports the following properties:
+
+
+ id
+ this is an integer and should be unique as it used to identify the map source
+
+
+ label
+ the text displayed in the map's source selection dialog
+
+
+ hostname
+ the server's hostname (eg. "tile.openstreetmap.org")
+
+
+ url
+ the parametrized address of the tile, in the spirit of C printf format, with 3 "%d" fields for X, Y and Z (zoom level) (eg. "/%d/%d/%d.png")
+
+
+
+ The VikTmsMapSource allows to declare any TMS service. It supports the following properties:
+
+
+ id
+ this is an integer and should be unique as it used to identify the map source
+
+
+ label
+ the text displayed in the map's source selection dialog
+
+
+ hostname
+ the server's hostname (eg. "tile.openstreetmap.org")
+
+
+ url
+ the parametrized address of the tile, in the spirit of C printf format, with 3 "%d" fields for X, Y and Z (zoom level) (eg. "/%d/%d/%d.png")
+
+
+
+ The VikWmscMapSource allows to declare any WMS or WMS-C service. It supports the following properties:
+
+
+ id
+ this is an integer and should be unique as it used to identify the map source
+
+
+ label
+ the text displayed in the map's source selection dialog
+
+
+ hostname
+ the server's hostname (eg. "tile.openstreetmap.org")
+
+
+ url
+ the parametrized address of the tile, in the spirit of C printf format, with 4 "%s" fields for bounding box coordinates (eg. "/coord=%s,%s,%s,%s")
+
+
+
+
+
+
+ Go-to search engines
+ It is possible to add new new search engines for the "Go-To" feature. The file is ~/.viking/goto_tools.xml.
+ An example of the file in the distribution doc/examples/goto_tools.xml.
+ Currently, there is a single object class available: VikGotoXmlTool. Such feature allows to declare any search engine using a XML format as result.
+ The related properties are:
+
+
+ label
+ the text displayed in the Go-To dialog
+
+
+ url-format
+ the parametrized address of the query, in the spirit of C printf format, with a single "%s" field (replaced by the query string)
+
+
+ lat-path
+ XML path of the latitude (eg. /root/parent/elem)
+
+
+ lat-attr (optional)
+ name of the attribute (of previous element) containing the latitude
+
+
+ lon-path
+ XML path of the longitude (eg. /root/parent/elem)
+
+
+ lon-attr (optional)
+ name of the attribute (of previous element) containing the longiude
+
+
+
+ As a facility (or readability) it is possible to set both path and attribute name in a single property, like an XPath expression. To do so, simply set both info in lat-path (or lon-path) in the following format: /root/parent/elem@attribute.
+
+
+
+ External tools
+ It is possible to add new external tools. The file is ~/.viking/external_tools.xml.
+ An example of the file in the distribution doc/examples/external_tools.xml.
+ The VikWebtoolCenter allows to declare any Webtool using a logic based on center coordinates and zoom level value.
+ The related properties are:
+
+
+ label
+ the text displayed in the menu entry
+
+
+ url
+ the parametrized URL to open, in the spirit of C printf format, with 2 "%s" and a "%d" fields for X, Y and Z (zoom level) (eg. "http://hostname/?lat=%s&lon=%s&zoom=%d")
+
+
+
+ The VikWebtoolBounds allows to declare any Webtool using a logic based on bounds coordinates.
+ The related properties are:
+
+
+ label
+ the text displayed in the menu entry
+
+
+ url
+ the parametrized address of the tile, in the spirit of C printf format, with 4 "%s" fields for left, right, bottom and top (eg. "http://hostname:8111/load_and_zoom?left=%s&right=%s&bottom=%s&top=%s")
+
+
+
+
+
+
+ Routing engine
+ It is possible to declare new routing engines. The file is ~/.viking/routing.xml.
+ An example of the file in the distribution doc/examples/routing.xml.
+ The VikRoutingWebEngine allows to declare a routing engine available via HTTP.
+ The related properties are:
+
+
+ id
+ a string, should be unique as it used to identify the routing engine
+
+
+ label
+ the text displayed in the menu entry
+
+
+ url-base
+ the base URL of the web service (eg. "http://hostname/service?")
+
+
+ url-start-ll
+ the part of the URL setting the starting point location, parametrized in the spirit of C printf format, with 2 "%s" for coordinates (eg. "&start=%s,%s")
+
+
+ url-stop-ll
+ the part of the URL setting the end point location, parametrized in the spirit of C printf format, with 2 "%s" for coordinates (eg. "&stop=%s,%s")
+
+
+ url-via-ll
+ the part of the URL setting via point location, parametrized in the spirit of C printf format, with 2 "%s" for coordinates (eg. "&via=%s,%s")
+
+
+ url-start-dir
+ the part of the URL setting the starting point location for direction based routing, parametrized in the spirit of C printf format, with one "%s" for direction (eg. "&start=%s")
+ (Optional)
+
+
+ url-stop-dir
+ the part of the URL setting the end point location for direction based routing, parametrized in the spirit of C printf format, with one "%s" for direction (eg. "&start=%s")
+ (Optional)
+
+
+ referer
+ an URL to serve as referer for the HTTP request (eg. "http://hostname/")
+
+
+ follow-location
+ the max depth of recursive redirections
+
+
+
+
+
+
+ Remote File Datasources
+ It is possible to add web references expected to return a file which can then be opened directly or converted via GPSBabel.
+ The file is ~/.viking/datasources.xml.
+ An example of the file is in the source distribution doc/examples/datasources.xml.
+ The VikWebtoolDatasource allows to declare any URL using logic based on coordinates.
+ The related properties are:
+
+
+ label
+ the text displayed in the menu entry
+
+
+ url
+
+ the parametrized URL to open in the spirit of C printf format, with up to 7 "%s" values. e.g. http://hostname/getfile?lat=%s&lon=%s
+ The order and meaning of these parameters is given by the url_format_code below
+
+
+
+ url_format_code
+
+ A string describing the parametrized URL substitution parameters, each character represents how to translate each term.
+ B = Bottom of the current view i.e. minimum latitude
+ L = Left of the current view i.e. minimum longitude
+ T = Top of the current view i.e. maximum latitude
+ R = Right of the current view i.e. maximum longitude
+ A = center lAtitude of the current view
+ O = center lOngitude of the current view
+ Z = OSM Zoom value of the current view. See Zoom Levels
+ Thus for the url example above then the format code should be AO
+
+
+
+ file_type
+
+ This value is passed on for the -i parameter in interfacing with GPSBabel.
+ If it is not defined then the returned file is interpreted internally as a GPX file.
+ Possible values such as 'kml', 'mapsource' etc.. can be used. See GPSBabel File Formats for the full list.
+
+
+
+
+
+
+
+ More
+ Note that, on UNIX like systems, the extension files (maps.xml, goto_tools.xml, external_tools.xml, datasources.xml) are also searched in /etc/viking and /usr/share/viking directories (or related in your system).
+ The XDG_DATA_DIRS environment variable can be used to change these directories.
+ The XDG_DATA_HOME environment variable is also used (if set) to look for these extension files.
+
+
+
+ Miscellaneous Settings
+ Various individual values are automatically saved between &app; sessions in the ~/.viking/viking.ini file.
+ This file is not intended to be manually edited, but since it is a plain text file it can be changed if desired.
+ Some values in this file are read only, in the sense that there is no way to set it other than by manually entering in the keys and values (the key will not exist in the file otherwise). This allows some fine tuning of &app; behaviours, without resorting to recompiling the code. However is it not expected that these values should need to be changed for a normal user, hence no GUI options for these have been provided.
+ Here is the list of the read only keys and their default values.

+ trkpt_selected_statusbar_format=KEATDN
+ This string is in the Message Format Code
+
+
+
+
+ Message Format Code
+ Currently for ease of implementation the message format code is a string of characters.
+ Each character represents what should be inserted in relation to a Trackpoint.
+ One day it might evolve into something more user friendly with a frontend to control it, perhaps allowing arbitary text too. However for now at least some control is offered :)
+
+
+
+ Character Code
+
+ G = Some text to display at the start of the message - GPSD
+ K = Some text to display at the start of the message - Trkpt
+ A = Altitude of a Trackpoint
+ S = Speed of a Trackpoint
+ C = Course of a Trackpoint
+ L = Location of a Trackpoint
+ T = Time of a Trackpoint
+ M = Time diff of a Trackpoint from the previous trackpoint
+ X = Number of satellites used in the trackpoint fix
+ D = Distance of the trackpoint from the start of a track (following along the track)
+ P = Distance difference of the trackpoint from the previous trackpoint
+ N = Name of track to which the trackpoint belongs
+ E = Name of the trackpoint
+
+
+
+ Output Notes
+
+ If the output has * after it, then the value has been calculated via interpolation (such as speed when the Trackpoint does not contain a speed value).
+ If the output has ** after it, then difficulties were encountered in trying to work the value so probably a default of 0 will be shown.
