Hi Andrzej Thanks for that. However, I find that Transparency still allows for DEM to be visible on the other maps I create. Interesting about the DEM having 5 layers and only 4 layers in my data Again , this normally doesn't cause a problem but it is an issue. I only include the dem files in the tdb when I upload the map to my device. Basecamp doesn't seem to complain. My point was , that for some strange reason the/.hgt file needed for this area /gets ignored by BuildDEMfile , but not always - see below Maps anywhere else don't cause a problem - @ Frank 1) if I add dem files to kent-latest1.osm.pbf from, Geofabrik the 'missing' .hgt file gets included and*the**/whole of Kent /**displays DEM* 2) If I use the small map OR 68775599.osm.pbf then the problem happens only the top part gets DEM - see picture It perhaps has something to do with having to include a sea .hgt r Nick On 23/11/2017 13:00, Andrzej Popowski wrote:
Hi Nick,
there are several problems with your map.
You have created a transparent map without background. I think background object 0x4A is needed for DEM shading.
You have created DEM with 5 layers, while you got only 4 layers of data in your map. Programs probably won't accept DEM with excessive number of DEM layers.
TDB of your map doesn't contain references to DEM.
