Thanks for the quick fix Gerd! I have tested a few tiles, seems working as expected with r4035. ________________________________ Hi Minko, Since r4027 single zipped hgt files (*.hgt.zip) caused problems, mkgmap remembered the wrong name and tried to find the file again and again (silentiy and without success) for each height value needed for the DEM calculation.
