Re: [mkgmap-dev] BuildDEMFile problem
Hi Nick, it's a really small piece. But 0,157° x 0,0685° and dlon=0,00027761 are about 565 x 246 points. That are a lot of 64x64 DEM tiles. I don't think, that's a problem. Can you put the ready card (still without DEM's) to http://www.pinns.co.uk/errs/ or whereever? What say mapsource to your map? Frank
Hi Frank gmapi at http://www.pinns.co.uk/err/mapdem.gmap.zip It might be that the dem file is 'empty' but basecamp doesn't show darkened '3d ness' of a landscape Somehow, my mapsource doesn't show 3d maps On 23/11/2017 08:13, Frank Stinner wrote:

Hi Frank I have a picture showing problem when I parse 68775599.osm.pbf It appears that for some reason the bottom .hgt file gets ignored. http://www.pinns.co.uk/err/ 68775599.osm.pbf http://www.pinns.co.uk/err/kent_half_half.png On 23/11/2017 08:25, osm@pinns 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. -- Best regards, Andrzej
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:
