Hi Nick I dont know what you mean, but the missing part is the whole NL above N52.2 and also everything western from E5.0 So that means N53E004.hgt -N53E007.hgt are not processed and also the tiles N52E004.hgt-N52E007.hgt are missing in the map. They are available in the DEM folder. ________________________________ Van: mkgmap-dev <mkgmap-dev-bounces@lists.mkgmap.org.uk> namens osm@pinns <osm@pinns.co.uk> Verzonden: donderdag 26 oktober 2017 00:43 Aan: mkgmap-dev@lists.mkgmap.org.uk Onderwerp: Re: [mkgmap-dev] a new DEM-File Option Hi Minko If you export a small section from the openstreetmap area which doesn't have a tile then it should tell you the name of the missing .hgt? You can then search for it on https://e4ftl01.cr.usgs.gov/SRTM/
