Regarding tiles covering Caspian Sea (N37E051 to N44E049), I thought
it's height would be 0, but if the real height is -29m then they should
not be removed from known-hgt.txt. 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.

Hi Carlos,
not sure what to do with this. Seems your patch removes the files which are
listed here:
https://www.opentopodata.org/notes/invalid-srtm-zips/
My SRTM directory contains the listed files and they show a constant height of
-29m as stated in the linked page.
My understanding is that you don't have those files, but you should have. A
non-existing file is treated like a file with height 0.

Betreff: [mkgmap-dev] Deletion of unneeded hgt files
Attached patch deletes some hgt files which correspond to ocean areas
from known-hgt.txt file. They just lead to confusing warnings when
running mkgmap to generate a map with DEM.
