Hi there

I currently use TTQV Navigation software on a CarPC for offroad
navigation with raster maps.

But I would like to use an open source software instead.
Would gpsVP be the right software?

Or World Wind?

I need:
- Import of raster maps with the TTQV cal files. Including ECW format.
- Moving map
- Touchscreen Operation including virtual keyboard input for track and
waypoint names
- Capture and display Tracks and waypoints

I can help writing software. I have done my own open source software,

Or maybe there is another open source software that comes close to

Thanks & regards
