Doesnt matter which zoom level I use. Map in XCSoar is much more detailed in any zoom level.
Where do I change the topology line setting in LK8000?

I've made a video. Check it out.

I successfully used LKmaps desktop to create a DEM & LKM for SE Mass USA . However i can't see any terrain elevation changes in LK8000. Terrrain shading is set to High Contrast. There are some hilly areas in the NW corner that DO show up in the NEW ENGLAND maps provide in the LKMAPS app. The bounding area i used is:

Top: 42.36 Left:-71.93 Right -70.52 Bottom:

Terrain pixel size is set to 90meters. LKM was created in offline mode.

I tried opening the .Dem file created by LKmaps in QGIS but QGIS choked on the file.

Is the LK .DEM format the standard .DEM format?

Ultimately my goal is a higher resolution map covering a much smaller area than the standard NEW ENGLANG map that will show terrain of lower hilly areas

'.dem' file is not standard.
- what is the size of dem file ?
- what version of LK8000
- what platform ? ( PC, Android, WinCE ... ) ?
- have you checked the Runtime.log for loading error ?

Not surprisingly - pilot error....i ASSUMED terrain would always be displayed when i panned in fly mode.

Terrain displays in sim mode. When it's in Fly mode terrain is not displayed unless your GLIDER is inside the terrain area. Given limited memory resources this makes some sense although it seems as though panning to the area should temporarily display terrain.


What is significance of log message "WARN Topology, shape bounds reading failed, fallback to mode0"

again, Thank You for your prompt replys and patience

your topology file look invalid, or something is wrong with cache ...

we need to check...

I tried to create terrain for a large area (the whole of UK). LKmaps (PC desktop version) got sucked at downloading one of the tiles. After restarting I can't create terrain even for the smallest area. After clicking 'generate terrain nothing happens ( I don't see typical downloading tile bar progress, just see one blue square without any information about which tile is being downloaded). I tried reinstalling LKmaps, but it didn't help. It looks like all my settings are remembered from previous installation.

Where (in which folder) are all temporary downloaded files and setting stored? I would like to delete everything to get a clean new installation which will hopefully work again.
