Trekarta (former MapTrek) is designed for hiking, geocaching, off-roading, cycling, boating and all other outdoor activities. It uses offline maps, so you do not need to have internet connection.
Trekarta is developed as a hobby for personal use but is generously shared to public on as-is basis. Developers are welcome to contribute to the project. Specifically experts in OpenGL and PostGIS are much needed.
With it, you can easily import places and tracks from GPX and KML data formats or create waypoints in application and share them to others. It lets you write the track of your journey, even in the background, so you will never get lost and be able later see where you've been.
Primary features
Offline Maps
Trekarta uses OpenStreetMap based vector maps that are lightweight, offline and are constantly enhanced by contributors. Maps contain detailed topological data with elevation contours. Some map elements can be filtered out for cleaner look. Trekarta has built-in hillshades support.
You can add custom maps in SQLite or mbtiles format to cover your area of interest. Custom maps will be shaded as well. Such maps can be created by yourself with SAS.Planet application from almost any online source or converted with MapTiler and other applications from other map formats.
Tracks
Trekarta is designed to record tracks of your journey. Simply press a button when you start and press it once more when you finish. You can quit the application if you do not need to look at the map, the track will be recorded in the background.
