-Map
-GeoRef
+Enables off line usage

-Properties - Layer setup / configuration settings
-Cut
-Copy
-Paste
-Delete
-Visibility - This checkbox on the Layers Panel controls whether the layer is shown in the viewport or not
-
+
-The cut/copy/paste options can be accessed in a variety of ways once the layer has been selected:
+ 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.
-
-Standard keys: Ctrl+x|c|v
-Main menu Edit
-From the right click menu
-Buttons at the bottom of the Layers Panel
-
+
+
-See the individual section for detail about each layer.
+ 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.
-
-
+
-TrackWaypoint layers display GPS data (tracks and waypoints).
-
-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.
+ 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.
+
-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.
+ 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)

+The layout of the cache on disk itself can be controlled via a per Map Layer property.
+

+ If the keyboard shortcut is already in use you will not receive any notification that new action replaces the old action.
+ This is probably why most distributions have this facility disabled by default.
+ Thus you will need to enable Editable menu accelerators for your system.
+ Check the Desktop Menu and Toolbar Control or other User Interface preferences for this setting.
+
-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
+Tracks vs Routes
-The layer (all tracks and waypoints) can be exported to a file GPX, GPSPoint, GPSMapper or Google's KML format.
+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.
-Version1.1+: An individual track can be exported to a GPX file via the track menu.
+Q. When planning a route what difference does it make if it's a route or a track?
-
-
-New Waypoint
-This opens a dialog box to create a new waypoint. A default name will be suggested and the default position is the center of the viewport.
+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.
-
-
-Add Wikipedia Waypoints
-This gets 'interesting' points from Wikipedia for the specified view: either within the extent of layer bounds or within the current viewport boundary.
+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.

- &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.
+Besides it's own file type, &appname; can open (and save to via export methods) GPX and KML file types.
- Warning!
-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.
+&appname; does not handle GPX 1.1 particularly well - it prefers GPX 1.0
-Currently &appname; does not support the OAuth mechanism.

-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.
+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

-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).
+FileAcquireImport GeoJSON File
-If the waypoint has an associated image, then the Geotag information may be updated, either with updating the file's modification timestamp or not.

+On the Image Settings you can move the image around the page and scale the image up / or down.
-

-Version1.3+: Geotag Images
+Generate Image File
-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.
+Located on the FileGenerate Image File menu only.
-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.
+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.
-
-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.
+You should have previously downloaded the tile images for the chosen zoom level,
+otherwise the image produced will have missing sections.
-
+
-Various options allow control of how the geotagging process is performed:
+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.

-Images - Add the images used for geotagging
-Create 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.

+Properties - Layer setup / configuration settings
+Cut
+Copy
+Paste
+Delete
+Visibility - This checkbox on the Layers Panel controls whether the layer is shown in the viewport or not
+
-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]

+
+Standard keys: Ctrl+x|c|v
+Main menu Edit
+From the right click menu
+Buttons at the bottom of the Layers Panel
+
-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.
+Default values used for each layer's properties can be altered via the EditLayer Defaults menu options.
-The current data server is: NASA STRM 2.1.
+See the individual section for detail about each layer.
+
+
+TrackWaypoint Layer
-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.
+TrackWaypoint layers display GPS data (tracks, routes and waypoints).
+
+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.
-
-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"
+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
+layers panel to show all the individual items and then typing the name of the track, route or waypoint.

-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.
+The containing Tracks, Routes or Waypoints sublayers are only shown when items of that type exist.
+To start creating them enter into a create mode via either the Create toolbar commands or the New menu commands.
+
-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.
+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.
+
-Inbuilt maps include various Terraserver (Primarily USA coverage) and OpenStreetMap (OSM) ones and more:
+By default routes are coloured red. Tracks are automatically assigned a spread of colours.

-&appname; can be configured to handle additional maps. See Extending &appname; for further detail.
+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
-Download Missing Onscreen Maps
-This requests map tiles for areas of the viewport that do not currently have one.
+The layer has a context menu with several operations.
-
-Download New Onscreen Maps
+View Layer
-This requests map tiles only if the maps are older than the Tile Age preference.
+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).
-Reload All Onscreen Maps
+View
+
+View All Tracks
-Force a refresh of all visible map tiles.
+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
+
+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
+
+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).
+
+
-
+
-Aggregrate Layer
+Goto Center of 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, although it can be renamed.
+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
-This layer type is useful for grouping other layers, especially TrackWaypoint 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...
-
+This opens a dialog box to enter a name of waypoint to search for. If it is found the viewport is centred on it.
+
-Thus one can have a list of all your tracks, but groups can be shown or not using the relevant layers visibility checkbox.
+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
-This layer only has one operation: New Layer
-
-
-New Layer
+The layer (all tracks, routes and waypoints) can be exported to following file formats:
+
+
+
+ GPX
+
+
+ GPSPoint
+
+
+ GPSMapper
+
+
+ Google's KML
+
+
+ Any GPSBabel File Formats

+ GeoJSON. Via the program togeojson
+ This option will not be available if the program is not detected on your system.
+ See here for the installation method.
+
+
-Add a new layer of the selected type.
+Version1.1+: An individual track can be exported to a GPX file via the track menu.
-
-
-GeoRef Layer
+Finish Track or Route
-This layer allows one to use any image as a map. You will need to tell it how to align the map to a position in the world and the scale of map.
+Selecting this option ends the creation of that individual track or route.
-Layer Operations
-Zoom to Fit Map
+
-Automatically set a zoom level to see the entire map coverage.
+This is only available when a track or route is being created by the or tools.

-Tools
+Acquire
-You can use the scroll wheel and the right-click to zoom and pan no matter what tool you are using.
+This offers the same choice from methods as on the File menu.
+However when invoked from here, the results will be stored in this layer (instead of creating a new one).
+
+
+Upload
+
+Upload to GPS
-Scroll: zoom in and out keeping the mouse over same location
+This opens a dialog to select the GPS Device and port to which the layer information will be transferred.
-Ctrl-scroll: pan north-south (also Ctrl-up, Ctrl-down)
+The types of GPS information (tracks, routes or waypoints) to be transferred can be selected.
-Shift-scroll: pan east-west (also Ctrl-left, Ctrl-right)
+Tracks, Routes or Waypoints that are invisible will not be transferred.
+
+
+Upload To OSM
-Ctrl-shift-scroll: zoom in and out, without changing the center (also Ctrl+, Ctrl- [*not* KeyPad +/-])
+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;
-Left or Middle-click: make the clicked point on the map the center
+ &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.
+
-Middle-click and drag: pan
+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.
+
+
-Pan
-
-Pan moves the viewpoint. A single click centers the viewport at that point, whereas click and drag dynamically moves the view around.
-This is the default tool.
-
-
-This mode can also be entered by the keyboard shortcut Ctrl+Shift+P

+
+
+Filter
+Simplify All Tracks
-Zooms in and out on the clicked part of the map or by the selected area.
+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.
+
+Compress Tracks
-This mode can also be entered by the keyboard shortcut Ctrl+Shift+Z
+Enables compression of tracks and routes via GPSBabel's Crosstrack simplify method.
+It opens a dialog to request the Error factor value which is the maximum allowable error that may be introduced by removing a single point.
+It is expressed a distance in units as specified by the distance option.
+Thus a higher value will remove more points.
+The result is put into a new layer.
+
+Remove Duplicate Waypoints
-Ctrl + left or right click: Zoom in/out and center the map on the clicked location
+Remove Duplicate Waypoints - fairly self explainatory, with the results created in a new layer.
+
-Shift (and hold) + left mouse button: Draws a bounding box area on which to zoom in. The zoom action is performed when the left mouse button is released.
+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.
+
+
-Ruler
+Filter With Trackname
-The ruler is used to measure the bearing and distance between two points: Click on first point and then move the mouse point around - the values will be continually updated.
-A second click will 'freeze' the ruler at that point.
+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
+
-This mode can also be entered by the keyboard shortcut Ctrl+Shift+R
+The result is generated in a new Track/Waypoint layer.
-Version1.1+: Select
-
-The select tool allows one to choose any waypoint or track by clicking on it (or reasonably near) in the viewpoint.
-
-
-ATM to select a track one must actually click on a trackpoint, which is also selected.

+
+
+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.
+
+

+
+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.

+
+
+
+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 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.
+
+
+
+Geotag Images...
+

+
+Offers a subset of the track utilities.
+Currently only setting the altitude from DEM data methods are available.
+
+
+
+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) against a specific waypoint or via interpolation against a specific track or all tracks in the TrackWaypoint layer - depending on how it is invoked.
+
+
+When geotagging against tracks, 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.
+
+
+
+Empty Item
+
+There are several options to quickly delete a subsection of data:
+

+
+
+
+
+
+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 (subject to the Alpha compositing property).
+
+
+Some maps are continually improving over time (e.g. OpenStreetMap) thus &appname; employs a caching mechanism to avoid redownloading data (see ).
+However a forced refresh for the current view can be made via the Reload All Onscreen Maps option or Ctrl+F5.
+
+Online Map Tile Providers
+
+You will need an open internet connection when you are downloading maps these following map types, 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.
+Inbuilt maps include various OpenStreetMap (OSM) ones and more:
+
+
+
+Bing Bird's Eye (Aerial) Maps (&appname; Version1.2+)
+OpenStreetMap (Mapquest) - This is the default (&appname; Version1.3+)
+OpenStreetMap (Mapnik)
+OpenStreetMap (Cycle)
+OpenStreetMap (Transport) (&appname; Version1.3+)
+OpenStreetMap (Humanitarian) (&appname; Version1.5+)
+NASA BlueMarble
+
+
+
+&appname; can be configured to handle additional online map resources. See for further detail.
+
+
+Offline Map Tilesets
+
+Some map types supported are for on disk tile formats:
+
+
+
+
+ On Disk OSM Tile Format
+ This is equivalent to any map set with OSM Cache Layput.
+
+MBTiles File
+OSM Metatiles
+
+
+Of course you need to have acquired or generated these tilesets yourself.
+
+
+Map Layer Properties
+
+Configurable properties:
+
+
+
+ Map Type. The kind of map this layer displays.
+ Map types are dependent on the current mode.
+
+Maps Directory. Not applicable for MBTiles Map type since it is a single file.
+Cache Layout. Viking or OSM. See . Only applies to maps from online tile providers.
+Map File. Ony applicable for MBTiles Map type since it is a single file.
+
+ Alpha. Control the Alpha value for transparency effect using a value between 0 and 255 with the default being 255 for a fully solid image.
+ Zero is fully transparent. A value of around 160 can be useful for blending views of multiple map layers (when applied to the upper most map layer).
+
+Autodownload Maps. This can be useful to turn off when you are not online to avoid pointless download requests or may be keep a map in a 'historical' state.
+e.g. perhaps in case a current map rendering is broken.
+Autodownload Only Gets Missing Maps. Using this option avoids attempting to update already acquired tiles.
+This can be useful if you want to restrict the network usage, without having to resort to manual control. Only applies when Autodownload Maps is on.
+Zoom Level. Determines the method of displaying map tiles for the current zoom level.
+Viking Zoom Level uses the best matching level, otherwise setting a fixed value will always use map tiles of the specified value regardless of the actual zoom level.
+
+
+
+
+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.
+
+
+Please respect the usage policy of the tile set provider.
+Such as OSM Tile Usage Policy.

+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.
+Each column header is clickable and will reorder the list according to that particular column.
+
+
+This table may be invoked from a variety of different layer levels and will then list only the relevant tracks (and/or routes).
+
+Aggregate Layer: Lists Tracks and Routes and the TrackWaypoint Layer they are in
+TrackWaypoint Layer: Lists Tracks and Routes
+TrackWaypoint Track sublayer: Lists Tracks only
+TrackWaypoint Route sublayer: Lists Routes only
+
+
+
+
+
+
+Hovering the mouse over an entry will show a tooltip of the comment or description if it is available.
+
+
+Each entry in the track list can be selected and on mouse right click offers these options:
+
+View. Move the viewport to the area of the item and highlight it.
+Statistics. Opens the Properties dialog on the tab. Note this will close the track list dialog.
+
+
+
+
+Waypoint List
+
+Selecting this opens a dialog listing all the waypoints to give a overview of the waypoint information.
+Each column header is clickable and will reorder the list according to that particular column.
+
+
+This table may be invoked from a variety of different layer levels and will then list only the relevant waypoints.
+
+Aggregate Layer: Lists Waypoints and the TrackWaypoint Layer they are in
+TrackWaypoint Layer: : Lists Waypoints
+TrackWaypoint Waypoint sublayer: Lists Waypoints
+
+
+
+
+
+
+Hovering the mouse over an entry will show a tooltip of the description if it is available.
+
+
+Each entry in the list can be selected and on mouse right click offers these options:
+
+View. Move the viewport to the area of the item and highlight it.
+Properties. This will open the properties dialog. Note this will close the waypoint list dialog.
+Show Picture. If enabled, this will open the associated image in an external Image Viewer program.
+
+
+
+
+Visibility Options
+
+This offers a quick way to set all the visibilities of each item within the containing layer, rather than having to change each one individually.
+
+Show All. Ensures all items are set to be visible.
+Hide All. Ensures all items are set to be invisible. This is useful for then turning on single items afterwards so the display is not cluttered.
+Toggle. Inverts the visibility status of each item.
+
+
+
+
+Search by Date
+
+This opens calendar dialog to select a date to search by within this Aggregate layer.
+The first item that is found on that date will be selected.
+Tracks are searched first in preference over waypoints.
+
+
+
+
+
+
+
+Coordinate Layer
+
+This layer is allows drawing of grid lines on the viewport.
