Hi Carlos, please double check: I don't have files for N60E157, N72E057 and N77E083 I have a N64W180.hgt with a few non-zero values.
Results are in new patch. Gerd ________________________________________ Von: mkgmap-dev <[email protected]> im Auftrag von Carlos Dávila <[email protected]> Gesendet: Samstag, 3.

But they are no longer available from SRTM or ALOS. The other tiles removed in my patch are in open sea areas, so their height should be 0 and can be IMHO safely removed.
