Happy New Year to all! One user of my maps has reported that when he loads a gmapsupp with DEM in BaseCamp, it doesn't show shaded relief, while if he loads gmap version of the same map it does. I have confirmed the issue with a couple of maps and also that BaseCamp reads height information from gmapsupp, as it is displayed in the status bar along with coordinates. gmap version of the same maps does show both shaded relief and height info at all zoom levels. My DEM maps are generated with options below, just combining precompiled map data (51*.img) and DEM data (63*.img) tiles. gmapi command: java -ea -Xmx27G -jar mkgmap.jar --dem=hgt/ALOS --dem-poly=polygons/$mapa.poly --overview-dem-dist=128000 --gmapi-minimal${GMAPI_MINIMAL} --show-profiles=1 --road-name-config=${CONFIG} tmp/51${FID}*.img curvas/63${FID}*.img tmp/${ABR}5${FID}.txt gmapsupp command: java -Xmx27G -ea -jar mkgmap.jar --gmapsupp --road-name-config=${CONFIG} --route tmp/51${FID}*.img curvas/63${FID}*.img tmp/${ABR}5${FID}.typ --description="OSM $MAPA DEM" --no-tdbfile I then tried splitting map data with the same areas.list used to generate DEM tiles, so that both groups of tiles share the same bounding box, but it didn't work either. Only if map and DEM data are all compiled in the same run of mkgmap, gmapsupp shows shaded relief in BaseCamp. Does anybody know a way to get shaded relief from gmapsupp when using precompiled tiles?
