Thanks Felix, I'll try it. I just preferred to have separate DEM/contour lines tiles, but combining them will be OK. El 30/8/20 a las 18:02, Felix Hartmann escribió:
it's fine as long as you don't use empty maps. Just make a DEM contourlines layer. Not an DEM layer and a contourlines layer.

Hi Gerd Does it mean it is imperative DEM tiles have the same bounding box that tiles containing OSM data? I ask because I have recently tried building DEM img's with no OSM data (empty style) and then combining them with OSM tiles, in the same way I do with contour lines tiles, but MapSource crashes as soon as I click on "Show route profile" button. I would like to be able to reuse DEM tiles, so that it is not necessary to build them each time I update a map. This approach works fine for contour lines, but I didn't succeed for DEM.
