Viking aims to be easy to use, yet powerful in accomplishing a wide variety of GPS related tasks. It uses a hierarchical layering system to organize GPS data, maps, and other layer types with spatial data, such as coordinate lines.
Some of the things you can use Viking for are:
* Uploading and downloading waypoints, tracks to/from GPS. * Realtime GPS tracking and track recording. * Import and export of gpx files. * Preparing tracks and waypoints for trips using maps from services such as OpenStreetmap and Terraserver. You only need to upload the data to your GPS before you leave. The maps together with your tracks and waypoints can also be printed and used during the trip. * After trips, tracks and waypoints from GPS can be downloaded, stored, managed and reused in later trips. * Analyzing OHV and hiking trips, understanding where you went and how far you were from something. * Making waypoints and tracks to follow to easily get someplace you've never been before or don't have GPS data for but Terraserver maps exist for it. * Making maps with coordinate lines. * Analyzing speed at different places, adding waypoints where you forgot to mark one but did slow down or stop.
