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.

Layers

TrackWaypoint Layer

TrackWaypoint layers display GPS data (tracks and waypoints).

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.

Layer Operations

The layer has a context menu with several operations.

Export

The layer can be exported to a file GPX, GPSPoint or GPSMapper format.

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.

Track Properties

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.

The following colors are used in the elevation-distance graph:

• Brown profile: elevation data in graph
• Yellow: no elevation data
• Green: elevation data from DEM
• Red: speed

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.

Apply DEM data

If any DEM data is loaded, this will apply the DEM data to give the track elevation data.

Extend track end

Change the current tool to add track and add points to the end of the track.

Upload to OSM

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

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.

Waypoint Operations

Goto Geocache page

If the waypoint's name is in Geocache form (GCXXXXX) you can launch a web browser to go to the Geocache page.

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.

Download

To download data from the GPS, right-click the GPSLayer 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 in it, or copying and pasting or dragging waypoints/tracks from another layer). Then right-click the GPSLayer 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 GPSLayer properties dialog. Then right-cilck the layer and select "Start realtime tracking".

Tools

You can use the scroll wheel and the right-click to zoom and pan no matter what tool you are using.

Scroll: zoom in and out without changing center (also Ctrl+, Ctrl-)

Ctrl-scroll: pan north-south (also Ctrl-up, Ctrl-down)

Shift-scroll: pan east-west (also Ctrl-left, Ctrl-right)

Ctrl-shift-scroll: zoom in and out, keeping mouse over same location (like Google maps)

Middle-click: make the clicked point on the map the center

Middle-click and drag: pan

Zoom

Zooms in and out on the clicked part of the map.

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

You must have a TrackWaypoint Layer selected to use these.

New Waypoint

New Track

Right-click: undo one point

Ctrl: snap to trackpoint

Shift: snap to waypoint

Edit Waypoint

Click/drag: select/move a waypoint

Ctrl: snap to trackpoint

Shift: snap to waypoint

Right-click on waypoint: opens a menu with waypoint actions (the same menu accessed by right-clicking the waypoint in the layers panel)

Edit Trackpoint

Ctrl: snap to trackpoint

Shift: snap to waypoint

Show Picture

Uses eog to open a picture shown as a picture waypoint.

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.

Right-click: undo last routing

Ctrl: continue previous track

Georef Map Layer Tools

You must have a Georef Map Layer selected to use these tools.

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.

Georef move

Drag to move the georeferenced map.

Map Download

Click to download a single tile. Drag to download tiles in the dragged rectangle area.

Right-click to redownload bad/all tiles. Right-click and drag to redownload bad/all tiles in the dragged rectangle area.

DEM Download

Click to download and import a DEM file.
