103 <section id="introduction">
104 <title>Introduction</title>
106 &appname; aims to be easy to use, yet powerful in accomplishing a wide
107 variety of tasks. Some of the things you can use &appname; for are:
109 <itemizedlist mark="opencircle"><listitem>
111 Uploading and downloading waypoints, tracks and routes to/from GPS.
115 <para>Preparing tracks, routes and waypoints for trips using maps from services such as OpenStreetMap (OSM) and/or Terrasever.
116 The data is only needed to be uploaded to your GPS before you leave.
117 The maps together with your tracks, routes and waypoints can also be printed and used during the trip.
122 After trips, tracks and waypoints from GPS can be downloaded, stored, managed and reused in your (or your friends') later trips.
127 Analyzing Off Highway Vehicle (OHV) and hiking trips, understanding where you went and how far you were from something.
131 <para>Making waypoints, tracks and routes to follow to easily get someplace
132 you've never been before or don't have GPS data for but online
138 Making maps with coordinate lines.
143 Grouping data from multiple trips using a hierarchical data manager.
148 Analyzing speed at different places (to some degree), adding waypoints where you forgot to mark one but did slow down or stop.
153 Downloading and storing OpenStreetMap and/or Terraserver maps on your hard drive and looking at them later.
158 Editing routes or tracks and their trackpoints, joining and splitting up tracks and routes.
163 Show the live GPS position on the map (for use on a mobile device - e.g. a laptop). Not <trademark>Windows</trademark> at the moment.
168 Import track, route and waypoint files of various types via <application>GPSBabel</application>
173 View, create and update Geotagged Images (using EXIF data).
179 &appname; is under continual improvement: see the potential areas in the <ulink url="http://sourceforge.net/apps/mediawiki/viking/index.php?title=Main_Page#TODO_.2F_Ideas"><citetitle>Roadmap / Wishlist</citetitle></ulink>:
183 <title>Screenshot: OSM Cycle Map and Many Tracks</title>
185 <graphic format="JPG" fileref="figures/Viking-OSM-CycleMap-ManyTracks.jpg"/>
190 <section><title>General Concepts</title>
191 <section id="gc_layers" xreflabel="Layers"><title>Layers</title>
193 <emphasis>Layers</emphasis> is concept one may know from powerful graphics editors such as <application>Photoshop</application> or <application>GIMP</application>.
194 Instead of putting all the data on the same level, it is stacked (i.e. layered) with different data over one another.
195 This can be useful for analysis and general handling of various sets of data.
198 Unfortunately the downside of this complexity is remembering how differing layers of data can obscure other data.
201 The Map layers have <ulink url="http://en.wikipedia.org/wiki/Alpha_compositing"><citetitle>Alpha Compositing</citetitle></ulink>,
202 to create the appearance of partial transparency.
203 By controlling this value one can see data below it in the layer heirarchy for interesting effects.
206 <section id="gc_layers_panel" xreflabel="Layers Panel"><title>Layers Panel</title>
208 The panel on the left is called the <emphasis role="bold">layers panel</emphasis>.
209 It determines which layers and sublayers (such as tracks and waypoints)
210 are shown, and the order in which they are drawn. Layers on the
211 top of the layers panel list are drawn last. You can change the order by
212 drag and drop, or by selecting a layer and using the up and down
213 buttons at the bottom of the layers panel.
216 <section><title>Viewport</title>
218 The main &appname; area where the layer data is drawn, is called the <emphasis role="bold">viewport</emphasis>.
221 <section><title>Statusbar</title>
222 <para>This provides a readout of various information:</para>
224 <listitem><para>The currently selected (mouse pointer) tool</para></listitem>
225 <listitem><para>The number of items to process in the background - normally this the number in the map tile download queue</para></listitem>
226 <listitem><para>The zoom factor</para></listitem>
227 <listitem><para>The location of the mouse pointer (and potentially height information if DEM data is available)</para></listitem>
229 <para>When creating a track/route, the statusbar also displays some information about the track/route.</para>
231 <title>Statusbar</title>
233 <graphic format="PNG" fileref="figures/trw_statusbar.png"/>
236 <para>This part of the statusbar displays:
238 <listitem><para>The total distance of the track/route (including currently edited segment).</para></listitem>
239 <listitem><para>The bearing of the currently edited segment.</para></listitem>
240 <listitem><para>The distance of the currently edited segment.</para></listitem>
243 <para>For convenience, a zoom selector can be opened from the status bar. Simply left-click on the zoom factor.</para>
245 <title>The zoom selector available from status bar</title>
247 <graphic format="PNG" fileref="figures/zoom_status_popup.png"/>
252 <section><title>Projections</title>
254 &appname; supports differents projections:
260 <para>LatLon (also called EPSG:4326)</para>
263 <para>Mercator (also called Spherical Mercator)</para>
269 <section><title>Map Cache</title>
271 &appname; stores downloaded map tiles to disk for a couple of reasons:
274 <listitem><para>Enables off line usage</para></listitem>
275 <listitem><para>Reduces loading on the map tile provider</para></listitem>
278 The &appname; automatic caching strategy is two fold:
283 If the age of the tile on disk is less than the specified tile age (see <xref linkend="prefs"/>),
284 it will <emphasis>not</emphasis> attempt to contact the server to get a new version of the tile.
289 When the tile age has expired &appname; will attempt a <emphasis>refresh</emphasis> 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.
294 You can override the caching scheme by using right-click on the Map on the layers panel and selecting <guimenuitem>Redownload All Onscreen Maps</guimenuitem>, or <keycap>Ctrl+F5</keycap> for the top most map displayed. This will get the latest version held by the server.
298 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 <ulink url="http://help.openstreetmap.org/questions/102/i-have-made-edits-but-they-dont-show-up-on-the-map">I have made edits but they don't show up on the map</ulink>)
303 <section id="shortcut_keys" xreflabel="Shortcut Keys"><title>Shortcut Keys</title>
305 &appname; has several shortcut keys or key combinations for commands as listed in the main window along side the command.
308 Some function keys follow standard GUI behaviour:
311 <listitem><para><keycap>F1</keycap> Help (view this manual)</para></listitem>
312 <listitem><para><keycap>F5</keycap> or <keycap>Ctrl+R</keycap> Refresh the maps on screen</para></listitem>
313 <listitem><para><keycap>F10</keycap> Select the Menubar (in built behaviour)</para></listitem>
314 <listitem><para><keycap>F11</keycap> Full Screen</para></listitem>
315 <listitem><para><keycap>Ctrl+F5</keycap> or <keycap>Ctrl+Shift+R</keycap> Redownload the maps on screen</para></listitem>
319 Refresh attempts to get new maps only if the local tile cache time period has expired for any particular map tile.
320 Redownload gets all on screen maps from the server, ignoring the local tile cache.
324 Other function keys control turn on/off visibility of various elements:
327 <listitem><para><keycap>F3</keycap> Toggle visibility of the Toolbar</para></listitem>
328 <listitem><para><keycap>F4</keycap> Toggle visibility of the Menubar</para></listitem>
329 <listitem><para><keycap>Shift+F5</keycap> Toggle visibility of the Scale indicator on the viewport</para></listitem>
330 <listitem><para><keycap>F6</keycap> Toggle visibility of the Center Crosshairs on the viewport</para></listitem>
331 <listitem><para><keycap>F7</keycap> Toggle showing selected items (e.g. tracks or waypoints) in the highlight colour in the viewport</para></listitem>
332 <listitem><para><keycap>F9</keycap> Toggle visibility of the Layers Panel</para></listitem>
333 <listitem><para><keycap>F12</keycap> Toggle visibility of the Statusbar</para></listitem>
336 Standard shortcuts are provided for normal GUI operations: such as creating new files, opening, saving and exitting.
337 Then there are shortcuts specific to &appname; to switch projection modes, zoom in/out, create layers and switch the active tool mode.
338 For these combinations see the menu entry themselves.
342 <section><title>Tracks vs Routes</title>
344 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.
347 Q. When planning a <emphasis>route</emphasis> what difference does it make if it's a route or a track?
350 A. One difference is in how a GPS device navigates following the route or track.
351 Or you may want to consider interoperability with other software.
352 Otherwise it is probably best to use tracks as they are a superset of the route functionality.
355 For example on Garmin Etrex:
359 <para>Route following: Uses navigation mode with compass and estimated time to next point.</para>
360 <para>If following on road it can calculate a route on fly.</para>
361 <para>I (RN) always use this mode to follow pre planned routes.</para>
364 <para>Track following: Uses a <trademark>TracBack</trademark> mode</para>
365 <para>I (RN) never use this so I can't comment on how it actually compares to the route mode.</para>
369 There are often restrictions on the numbers of route points the GPS Device can handle - may be 250 or as little as 50.
370 This generally not a problem for single day routes, but needs managing for multi-day events or for highly detailed routes.
374 </section><!--General Concepts End-->
376 <section><title>File Types and the Main Window</title>
379 &appname; has it's own file type traditionally marked by the <emphasis>.vik</emphasis> file extension.
380 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...).
383 Besides it's own file type, &appname; can open (and save to via export methods) GPX and KML file types.
387 &appname; does not handle GPX 1.1 particularly well - it prefers GPX 1.0
391 By default &appname; opens a default blank window centered on the home location. This behaviour can be changed by the <xref linkend="prefs_startup"/>.
392 Each window contains menus, a toolbar, a viewport, layers panel and a statusbar.
393 Each section (apart from the viewport) can be hidden using the <xref linkend="shortcut_keys"/> or from the
394 <menuchoice><guimenu>View</guimenu><guisubmenu>Show</guisubmenu></menuchoice> choices.
397 One may consider each &appname; window to be a separate project - each with it's project <emphasis>Viking</emphasis> file.
398 However generally one window is enough for most purposes!
401 Several operations apply at the window level as follows next.
402 Also see <xref linkend="tools"/> for the operational modes that generally work in conjunction with a selected layer.
405 <section><title>New</title>
407 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>New</guisubmenu></menuchoice> menu and on the toolbar <guibutton>New</guibutton>.
410 This creates a new window with the default settings.
414 <section><title>Open</title>
416 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Open</guisubmenu></menuchoice> menu and on the toolbar <guibutton>Open</guibutton>.
419 This opens a file chooser dialog to select one (or more) files of the supported GPS data file types:
421 <listitem><para>Viking</para></listitem>
422 <listitem><para>GPX</para></listitem>
423 <listitem><para>KML</para></listitem>
424 <listitem><para>JPG</para></listitem>
428 GPX, KML and JPG files will be loaded into the existing &appname; view. A <emphasis>Viking</emphasis> file will be given a new window if the current window is already assigned.
432 &appname; handles more file types via the <link linkend="acquire">Acquire</link> methods below.
437 <section><title>Save</title>
439 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Save</guisubmenu></menuchoice> menu and on the toolbar <guibutton>Save</guibutton>.
442 If the current opened file is <emphasis>Viking</emphasis> file, this save will simply update it.
443 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 <emphasis>new name</emphasis> to save as a <emphasis>Viking</emphasis> file.
447 <section><title>Save As</title>
449 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Save As</guisubmenu></menuchoice> menu only.
452 This will ask for a <emphasis>new name</emphasis> to save as a <emphasis>Viking</emphasis> file (even it was already a <emphasis>Viking</emphasis> file).
456 <section><title>Append</title>
458 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Append</guisubmenu></menuchoice> menu only.
461 Selecting a <emphasis>Viking</emphasis> file from this method will join the file contents to the current window (instead of creating a new one).
462 GPX and KML files may also be appended, but this is exactly the same as the normal file open method.
466 <section id="acquire" xreflabel="acquire"><title>Acquire</title>
469 Available on the <menuchoice><guimenu>File</guimenu><guisubmenu>Acquire</guisubmenu></menuchoice> menu and from the <xref linkend="TrackWaypoint"/> layer menu.
472 If used from the <guimenu>File</guimenu> menu these methods place the results in a new TrackWaypoint layer.
475 If used from the <xref linkend="TrackWaypoint"/> layer menu these methods place the results in that TrackWaypoint layer.
479 <title>From GPS</title>
481 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>From GPS</guimenuitem></menuchoice>
482 Probably the easiest way of getting information from a GPS Device.
485 Select the GPS Device communication settings and then hit <guibutton>OK</guibutton>.
486 See the <link linkend="method_c">Getting Started</link> section for more info about the settings.
490 Some GPS devices (such as the <trademark>Garmin Nuvi 255</trademark>) support a native file system and write information to a <filename>Current.gpx</filename> file or similar. You will have to browse the file system on the device and open it directly.
496 <title>Import File With GPSBabel</title>
498 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>Import File With GPSBabel</guimenuitem></menuchoice>
501 Other formats can be imported that are supported by GPSBabel.
504 You need to select the file <emphasis>and</emphasis> the type of the file that is going to be opened,
505 since there is no automatic detection of the file kind.
510 <title>OSM Traces</title>
512 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>OSM Traces</guimenuitem></menuchoice>
515 See <xref linkend="osm_dl"/> section for more information.
520 <title>My OSM Traces</title>
522 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>My OSM Traces</guimenuitem></menuchoice>
525 See <xref linkend="osm_my_dl"/> section for more information.
530 <title>From Geotagged Images</title>
532 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>From Geotagged Images</guimenuitem></menuchoice>
533 Enables automatic creation of waypoints from geotagged images.
536 This menu opens a dialog to select such image files.
537 If the image files have geotag information in them, then a <xref linkend="TrackWaypoint"/> layer with named waypoints positioned at the location of each image with a thumbnail of that image is created.
542 <title>From Wikipedia Waypoints</title>
544 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>From Wikipedia Waypoints</guimenuitem></menuchoice>
547 This gets <emphasis>interesting</emphasis> points from Wikipedia for the specified view: either within the extent of layer bounds or within the current viewport boundary.
552 <title>From Routing</title>
554 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>From Directions</guimenuitem></menuchoice>
557 This gets a route from given directions.
562 <title>From URL</title>
564 <menuchoice><guimenu>File</guimenu><guimenuitem>Acquire</guimenuitem><guimenuitem>From URL</guimenuitem></menuchoice>
567 This gets a file from the entered URL.
568 File formats that can be opened are those supported by GPSBabel.
572 You need to select the type of the file that is going to be returned, since there is no automatic detection of the file kind.
577 </section> <!-- End Acquire -->
579 <section><title>Print</title>
581 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Print</guisubmenu></menuchoice> menu and on the toolbar <guibutton>Print</guibutton>.
584 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
585 cross hairs and the scale.
588 It uses a standard system print dialog using an image the size of the current viewport in pixel terms.
589 On the <emphasis>Image Settings</emphasis> you can move the image around the page and scale the image up / or down.
593 <section><title>Generate Image File</title>
595 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Generate Image File</guisubmenu></menuchoice> menu only.
598 Allows generation of larger (pixel) area images than the standard Print method above.
599 From the generated image you can use the facilities of the <application>Operating System</application> to print the image
600 or perform other actions.
603 You should have previously downloaded the tile images for the chosen zoom level,
604 otherwise the image produced will have missing sections.
608 Using large areas takes some time to process and due to the method used it may run out of memory to complete the operation.
609 Unfortunately under <trademark>Windows</trademark> systems it can not detect this failure and may crash the program.
610 So the maximum size is dependent on the capabilities of your system.
611 For instance the largest successful image generated on my (RN) Debian system is a pixel area of 20,000 x 20,000.
616 <section><title>Generate Directory of Images</title>
618 Located on the <menuchoice><guimenu>File</guimenu><guisubmenu>Generate Directory of Images</guisubmenu></menuchoice> menu only.
622 This is only available in UTM mode.
627 </section> <!-- End File Types -->
629 <section><title>Layers</title>
632 Layers supported by &appname; are:
635 <listitem><para><xref linkend="Aggregate"/></para></listitem>
636 <listitem><para><xref linkend="TrackWaypoint"/></para></listitem>
637 <listitem><para><xref linkend="GPS"/></para></listitem>

640 <listitem><para><xref linkend="Maps"/></para></listitem>
641 <listitem><para><xref linkend="GeoRef"/></para></listitem>
644 For each layer there are a few standard options:
647 <listitem><para>Properties - Layer setup / configuration settings</para></listitem>
648 <listitem><para>Cut</para></listitem>
649 <listitem><para>Copy</para></listitem>
650 <listitem><para>Paste</para></listitem>
651 <listitem><para>Delete</para></listitem>
652 <listitem><para>Visibility - This checkbox on the Layers Panel controls whether the layer is shown in the viewport or not</para></listitem>
655 The cut/copy/paste options can be accessed in a variety of ways once the layer has been selected:
658 <listitem><para>Standard keys: <keycap>Ctrl+x|c|v</keycap></para></listitem>
659 <listitem><para>Main menu <guimenuitem>Edit</guimenuitem></para></listitem>
660 <listitem><para>From the right click menu</para></listitem>
661 <listitem><para>Buttons at the bottom of the Layers Panel</para></listitem>
664 Default values used for each layer's properties can be altered via the <menuchoice><guimenu>Edit</guimenu><guisubmenu>Layer Defaults</guisubmenu></menuchoice> menu options.
667 See the individual section for detail about each layer.
671 <section id="TrackWaypoint" xreflabel="TrackWaypoint"><title>TrackWaypoint Layer</title>
673 TrackWaypoint layers display GPS data (tracks, routes and waypoints).
675 <para>One way to create new waypoints is to copy a
676 latitude/longitude coordinate pair, such as the one shown on most
677 geocaches, and paste it into an active TrackWaypoint layer. &appname; can
678 automatically recognize several variations of the lat/lon format.
681 By right-clicking on tracks, routes or waypoints in the <xref linkend="gc_layers_panel"/>, you can access many commands on them.
682 You can easily find a specific track, route or waypoint by expanding the appropriate containing Tracks, Routes or Waypoints sublayer in the
683 layers panel to show all the individual items and then typing the name of the track, route or waypoint.
687 The containing Tracks, Routes or Waypoints sublayers are only shown when items of that type exist.
688 To start creating them enter into a create mode via either the <guibutton>Create</guibutton> toolbar commands or the <guimenuitem>New</guimenuitem> menu commands.
692 The sublayers also offer right click menu options.
693 These are the same as those available at the TrackWaypoint level, but only those that relate to the sublayer type.
697 By default routes are coloured red. Tracks are automatically assigned a spread of colours.
701 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.
702 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).
705 <section><title>Layer Operations</title>
707 The layer has a context menu with several operations.
710 <section><title>View Layer</title>
712 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).
716 <section><title>View</title>
718 <section id="track_view_all"><title>View All Tracks</title>
720 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).
724 <section id="route_view_all"><title>View All Routes</title>
726 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).
730 <section id="wp_view_all"><title>View All Waypoints</title>
732 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).
738 <section><title>Goto Center of Layer</title>
740 This will automatically move the viewport to see the whole layer (i.e. tracks, routes and waypoints). It does not adjust the zoom level.
744 <section id="wp_goto"><title>Goto Waypoint</title>
746 This opens a dialog box to enter a name of waypoint to search for. If it is found the viewport is centred on it.
750 Note this search is not very clever and only finds exact matches.
751 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.
756 <section><title>Export Layer</title>
758 The layer (all tracks, routes and waypoints) can be exported to a file GPX, GPSPoint, GPSMapper, Google's KML format or any other format supported by GPSbabel.
761 Version1.1+: An individual track can be exported to a GPX file via the track menu.
765 <section id="finish_track"><title>Finish Track or Route</title>
767 Selecting this option ends the creation of that individual track or route.
771 This is only available when a track or route is being created by the <xref linkend="track_create"/> or <xref linkend="route_create"/> tools.
776 <section><title>New</title>
777 <section id="new_wp"><title>New Waypoint</title>
779 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.
782 <section id="new_track"><title>New Track</title>
784 This turns on the <xref linkend="track_create"/> tool.
787 <section id="new_route"><title>New Route</title>
789 This turns on the <xref linkend="route_create"/> tool.
794 <section><title>Geotag Images</title>
796 This starts the Geotagging Images dialog against all tracks in the layer.
797 See <link linkend="geotagging">Geotagging</link> for further detail.
801 <section><title>Acquire</title>
803 This offers the same choice from <xref linkend="acquire"/> methods as on the <guimenu>File</guimenu> menu.
804 However when invoked from here, the results will be stored in this layer (instead of creating a new one).
808 <section><title>Upload</title>
810 <section id="gps_upload"><title>Upload to GPS</title>
812 This opens a dialog to select the GPS Device and port to which the layer information will be transferred.
815 The types of GPS information (tracks, routes or waypoints) to be transferred can be selected.
818 Tracks, Routes or Waypoints that are invisible will not be transferred.
822 <section id="osm_upload" xreflabel="Upload To OSM" ><title>Upload To OSM</title>
824 This opens a dialog to upload all tracks and waypoints to <ulink url="http://openstreetmap.org/">OpenStreetMap</ulink> traces.
825 Useful if you are an OpenStreetMap contributor (you will need an OpenStreetMap account), these details can be stored in &appname; <xref linkend="prefs_osm"/>
828 &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.
832 The password is transferred <emphasis role="bold">unencrypted</emphasis> in every request sent to the OpenStreetMap server. This is due to the use of OpenStreetMap's basic authentication method.

862 <section><title>Filter</title>
863 <section><title>Simplify All Tracks</title>
865 This opens dialog to request the number of points each track will be simplified using <application>GPSBabel</application>. 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.
868 <section><title>Remove Duplicate Waypoints</title>
870 Remove Duplicate Waypoints - fairly self explainatory, with the results created in a new layer.
874 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.
880 <section id="filter_with_track"><title>Filter With <emphasis>Trackname</emphasis></title>
882 This runs <application>GPSBabel</application> on the layer using information from a previously selected track (select via the track menu "Use With Filter" option) with the following command types:
885 <listitem><para>Waypoints Inside This</para></listitem>
886 <listitem><para>Waypoints Outside This</para></listitem>
889 The result is generated in a new Track/Waypoint layer.

933 This shows several tabs for properties and useful statistics about a track or a route, including elevation-distance and speed-time graphs (if data is available).
934 Moving the mouse pointer over the graph displays values related to that point along the track.
935 You can click on these graphs to jump to the point in the track.

1026 Version1.1+: This centers the viewport on the track and selects the best zoom level to see it.
1030 <section><title>Combine</title>
1031 <section><title>Merge By Time</title>
1033 This operation repeatedly tries to merge the right-clicked track
1034 with tracks in the same TrackWaypoint layer. The tracks which are
1035 merged are those which have at least one trackpoint less than some
1036 threshold time away. This way, if you somehow end up with lots of small
1037 segments (say, caused by turning the GPS on and off) you can merge them
1038 easily into one track.
1042 This is not available on routes as they have no timestamps.
1047 <section><title>Merge With Other Tracks</title>
1049 This opens a dialog listing the other tracks in the same TrackWaypoint layer, from which one can select the other tracks to merge with.
1053 <section><title>Merge Segments</title>
1055 Combines track segments. Effectively removing track segment markers to leave one segment for the whole track.
1059 <section><title>Append Track or Route</title>
1061 Enable joining of a single track to the end of the current track.
1062 This opens a dialog listing the other tracks in the same TrackWaypoint layer from which one can make the selection.
1067 <section><title>Split</title>
1068 <section><title>Split By Time</title>
1070 This operation will split a single track into segments wherever the
1071 time interval between successive trackpoints is larger than some
1072 threshold. This is useful when processing raw NMEA GPS data, especially
1073 taken over a long time.
1077 This is not available on routes as they have no timestamps.
1082 <section><title>Split By Number of Points</title>
1084 Version1.2+: This operation will split a single track into segments by the number of points specified.
1085 This can be useful with devices which may have limits on the number of points it supports.
1089 <section><title>Split Segments</title>
1091 Splits track segments into new tracks.
1095 This is not available on routes as they do not have route segments.
1100 <section id='trkpt_split' xreflabel="Split at Trackpoint"><title>Split at Trackpoint</title>
1102 Splits the track at the currently selected trackpoint.
1105 The current track will finish at this trackpoint.
1106 A new track will start from a copy of this trackpoint.
1110 This is only enabled when a trackpoint is selected.
1116 <section><title>Insert Points</title>
1119 These options are only enabled when a trackpoint is selected.
1122 <section><title>Insert Point Before Selected Point</title>
1124 Inserts a track point halfway between the previous track point and the current track point.
1125 All track point properties are interpolated between the two points.
1128 <section><title>Insert Point After Selected Point</title>
1130 Inserts a track point halfway between the current track point and the next track point.
1131 All track point properties are interpolated between the two points.
1136 <section><title>Delete Points</title>
1137 <section><title>Delete Selected Point</title>
1139 Deletes the currently selected track point.
1143 This is only enabled when a trackpoint is selected.
1147 <section><title>Delete Points With the Same Position</title>
1149 Deletes subsequent points that have the same position (but have different timestamps).
1152 <section><title>Delete Points With the Same Time</title>

1167 These options alter the data of trackpoints of a track but not add or remove trackpoints.
1168 And don't seem to fit any other category :)
1170 <section><title>Apply DEM data</title>
1172 If any DEM data is loaded, this will apply the DEM data to give the track elevation data.
1173 Two ways of applying DEM data are offered:
1175 <listitem><para>Keep. Retains the existing elevation data of trackpoints and only those missing an elevation value are set.</para></listitem>
1176 <listitem><para>Overwrite. Elevation data are set on all trackpoints even if they already elevation values.</para></listitem>
1180 <section><title>Smooth Missing Elevation data</title>
1182 In various locations across the world, there are missing DEM values (AKA DEM Holes) from the SRTM data.
1183 This is particularly noticeable in mountainous areas.
1184 Two ways of applying elevation data to trackpoints that do not have elevation values are offered:
1186 <listitem><para>Interpolated. Missing elevation data is interpolated between the previous and next known values.</para></listitem>
1187 <listitem><para>Flat. Elevation data is filled in from the last previously known value.</para></listitem>
1192 <title>Convert to Track or Route</title>
1194 If this is a Route then it will convert it to a Track.
1197 If this is Track then convert it to a Route.
1201 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).
1206 <title>Anonymize Times</title>
1208 Timestamp information of a track can be shifted to be all offset from 1901-01-01.
1211 Thus the timestamps themselves will no longer reveal exactly when a track was taken.
1212 However the relative difference between the timestamps is kept thus one is still able to calculate some properties such as speeds along the track.
1216 This is not available for routes, as they have no timestamps.
1222 <section><title>Export Track as GPX</title>
1224 Version1.1+: This allows exporting the track as a GPX file by opening a file save dialog.
1228 <section><title>Extend Track End</title>
1230 Changes the current tool to add trackpoints to the end of the track.
1234 <section><title>Extend Using Route Finder</title>
1236 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.
1240 <section><title>Upload</title>

1256 <section><title>Use With Filter</title>
1258 This selects the track to be used in the <link linkend="filter_with_track">Filter With <emphasis>Trackname</emphasis></link> feature.
1262 This is not available on routes.
1267 <section><title>Edit Trackpoint</title>
1269 This opens the Trackpoint edit dialog. See <xref linkend="Trackpoint_edit"/>.
1273 This is only enabled when a trackpoint is selected.
1278 <section><title>Refine Route...</title>
1280 This function allows to request a Routing Engine in order to refine a given route.
1281 By "refining" we mean computing all real intermediates points between some given major points.
1282 This could be useful to compute a trip giving only the wished important steps.
1286 This is only available on routes.
1291 <section><title>View Google Directions</title>
1293 This option is only available on a track created using the Route Finder tool.
1296 Launch a web browser to see the Google directions page which yielded the route.
1300 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.

1322 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).
1325 If the waypoint has an associated image, then the Geotag information may be updated, either with updating the file's modification timestamp or not.
1326 This can be useful when the waypoint has been moved.

1373 <section id="geotagging" xreflabel="Geotagging"><title>Version1.3+: Geotag Images</title>
1375 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.
1378 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.
1382 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.

1454 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]
1457 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.
1460 The current data server is: <ulink url="http://dds.cr.usgs.gov/srtm/version2_1/">NASA STRM 2.1</ulink>.
1463 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 <application>curl</application> or <application>wget</application> to download them for an area.
1467 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.

2280 Use <menuchoice><guimenu>Layers</guimenu><guimenuitem>New Map Layer</guimenuitem></menuchoice>, and choose a suitable cache directory
2281 where you would like to store your tracks and click <guilabel>OK</guilabel>. Zoom to a
2282 comfortable level (I suggest 4 mpp) by clicking the left and right
2283 mouse buttons on the gray area where your tracks are. Now from the menu
2284 choose the <xref linkend="map_tool_dl"/> Tool. Click where you would like to download a
2285 map. Regardless of what tool you are using, the middle mouse button
2286 always pans. </para>
2289 You need an open internet connection when you are downloading maps.
2293 If you can no longer see your tracks or waypoints and only the map,
2294 it is because the layer named <emphasis>Map</emphasis> is <emphasis>ABOVE</emphasis> your TrackWaypoint layer that your GPS data is in.
2295 This means that it will be drawn last and on top of the other <xref linkend="gc_layers"/>.
2296 Look at the <xref linkend="gc_layers_panel"/> to the left which shows this order.
2297 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.
2298 Your tracks will now be drawn over the map.
2302 <section><title>Set Your Home Location</title>
2304 You can save the current center position of the viewport as the default location AKA the Home Location by

2457 <section><title>OpenStreetMap project</title>
2459 <ulink url="http://openstreetmap.org/">OpenStreetMap (OSM)</ulink> is a collaborative project to create a free editable map of the world.
2460 One of sources of data for this project is GPS tracks.
2461 &appname; supports this project via the GPS Traces methods, both uploading and downloading such data.
2464 Also see <ulink url="http://wiki.openstreetmap.org/wiki/API_v0.6#GPS_Traces"/> for further detail.
2466 <section><title>Uploading data to OpenStreetMap</title>
2468 It is possible to upload data directly from &appname; to OpenStreetMap.
2471 <title>Upload a layer</title>
2473 One solution is to upload whole a <xref linkend="TrackWaypoint"/> layer. To do this,
2474 simply select the layer and right click on it. Then, select <guimenuitem>Upload to
2479 <title>Upload a single track</title>
2480 <para>Another solution is to upload an individual track. Simply select the track and right click on it.
2481 Then select <guimenuitem>Upload to OSM</guimenuitem>.
2485 <title>Fill in the form</title>
2487 In both cases, &appname; will retain some information.
2488 The email field is the email you used to subscribed into OpenStreetMap.
2489 The password field is the password you used with this account.
2490 The filename is the name you want your upload has on the server. This information is displayed by the osm server.
2491 The description is some descriptive information.
2492 The tags field is a white separated list of tags.
2497 <section id="osm_dl" xreflabel="OpenStreetMap Traces Download"><title>Downloading Traces from OpenStreetMap</title>
2499 It is possible to download GPS traces directly from OpenStreetMap into &appname;.
2500 This feature can be really useful for checking existing data before uploading new ones.
2503 <title>Download all visible tracks</title>
2504 <para>One solution is to select
2506 <guimenu>File</guimenu>
2507 <guisubmenu>Acquire</guisubmenu>
2508 <guimenuitem>OSM traces...</guimenuitem>
2510 Each request can get up to 5,000 points.
2511 The dialog box allows setting which group of 5,000 points to get. These groups are known as <emphasis>Page Numbers</emphasis> which start at 0.
2512 Increasing the page number parameter allows one to request the subsequent sets of point groups.
2516 <section id="osm_my_dl" xreflabel="OpenStreetMap My Traces Download"><title>Downloading Your Own Traces from OpenStreetMap</title>
2518 It is possible to download any of <emphasis>your personal</emphasis> GPS traces previously uploaded to OpenStreetMap into &appname;.
2521 You will need to provide your OSM username and password to get the list of your OSM Traces.
2522 From this list you can select which traces to retrieve.
2523 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.
2529 <section><title>Geotagging</title>
2531 This assumes you already have a <xref linkend="Maps"/> layer enabled for ease of use (if not see above to get one).
2533 <section><title>Manual Positioning</title>
2535 This is useful for instances when you already know exactly where the image was taken (no need for tracklog).
2536 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.
2537 ATM this process only works on an individual image, so it will be tedious for handling lots of images.
2540 First create a <xref linkend="TrackWaypoint"/> layer or use an existing one; and select it in the <xref linkend="gc_layers_panel"/>.
2541 NB Make sure this layer is above the map layer in the Layers Panel list.
2542 Create a new waypoint (or move an existing one) to exact location desired:
2544 <listitem><para>Select the <xref linkend="createwptool"/> tool, then left click on the map at the location desired, choosing an image to associate with it in the new waypoint dialog</para></listitem>
2545 <listitem><para>Select the <xref linkend="select"/> tool, then left click on waypoint to be moved. Left click again and drag the waypoint to the location desired</para></listitem>
2547 Then using the Select tool left click on waypoint to select it, then right click to access the Waypoint properties menu, then choose
2548 <menuchoice><guimenu>Update Geotag on Image</guimenu><guisubmenu>Update</guisubmenu></menuchoice>
2551 The <guilabel>Update Geotag on Image</guilabel> options are only available when a waypoint has an image associated with it.
2555 <section><title>Automatic Positioning Against a Tracklog</title>
2557 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 -
2558 see <link linkend="howto_start">Getting Started</link>.
2559 It helps if this is the track that was recorded at the time you took some photographs!
2562 Select the track either from the layers panel on the left or via the viewport using the <xref linkend="select"/> tool.
2563 Then right click on it and chose the <menuchoice><guimenu>Geotag Images...</guimenu></menuchoice> leading you to the <xref linkend="geotagging"/> Dialog.
2566 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.
2567 If things are succesful, new waypoints with thumbnail images of the photographs will appear.
2568 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.
2570 <formalpara><title>Option: Overwrite Waypoints</title>
2572 This is particularly useful when one finds an attempt at geotagging gives wrong locations, often due to time offset issues.
2573 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).
2577 If you have multiple tracks in a TrackWaypoint layer, then invoking the <menuchoice><guimenu>Geotag Images...</guimenu></menuchoice> action on the layer
2578 will search all the tracks to find location matches.
2583 <section><title>GPS Real Time Location (Not <trademark>Windows</trademark>)</title>
2585 &appname; relies on <ulink url="http://www.catb.org/gpsd/">gpsd</ulink> to provide the current location from a real time feed from a GPS device.
2586 Unfortunately <application>gpsd</application> is not available on <trademark>Windows</trademark>,
2587 so currently this functionality is disabled in <trademark>Windows</trademark> builds of &appname;
2590 This assumes you already have a <xref linkend="Maps"/> layer enabled for ease of use (if not see above to get one).
2593 Turn on the GPS Device, ensure it has figured out it's location and plug it in to your computer.
2595 <section><title>Set Up GPS Layer</title>
2597 You will need a <xref linkend="GPS"/> layer. One can be added via <menuchoice><guimenu>Layers</guimenu><guisubmenu>Add GPS Layer</guisubmenu></menuchoice>.
2600 Adjust the <emphasis>Realtime Tracking Mode</emphasis> settings to interface with <ulink url="http://www.catb.org/gpsd/">gpsd</ulink> as necessary. Normally the defaults should suffice.
2603 Current Linux distributions should run <application>gpsd</application> automatically when a GPS Device is plugged in. Otherwise you may have to run <application>gpsd</application> manually.
2606 Then right-click the layer and select <guimenuitem>Start Realtime Tracking</guimenuitem>.
2607 Hopefully the viewport should jump to the GPS location.
2610 Troubleshooting checklist:
2612 <procedure><step><para>Confirm <application>gpsd</application> is running.</para></step></procedure>
2613 <procedure><step><para>Confirm on the GPS device it has a location.</para></step></procedure>

2618 <section><title>What to Do if &appname; Does Not Seem to Work</title>
2620 In order to get some information about what &appname; is doing, start it in verbose debug mode via the command line:
2621 <programlisting>viking -dV</programlisting>
2624 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.
2625 E.g. Something like this for DEMs:
