Hi Frank, my understanding is that DEM describes a grit of height values and --dlon / --dlat describe the resolution of this grit. I wonder why these values are not in Garmin map units.

DEM files include only the strong compressed height data. That means, we have only coordinates for that points and their height. The shading makes the software on pc or gps. 2) yes, you can create more zoomlevels. That is necessary for gps because on gps every zoomlevel is visible for a few zoom's. I think, you should have for every maplevel (see options-file in mkgmap-style) its own zoomlevel. --dlon and --dlat is the distance between the points. Normally --dlon == --dlat, thats why you can omit --dlat. --dlon=0 is senseless, that means: no distance between the points. For more zoomlevels use multiple --dlon. The values are experimental: BuildDEMFile ... --dlon=0.00027761 --dlon=0.00049 --dlon=0.00075 --dlon=0.00106 --dlon=0.0017 --dlon=0.0025 Frank --- Diese E-Mail wurde von Avast Antivirus-Software auf Viren geprüft. https://www.avast.com/antivirus _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev _______________________________________________ mkgmap-dev mailing list mkgmap-dev@lists.mkgmap.org.uk http://www.mkgmap.org.uk/mailman/listinfo/mkgmap-dev
