Response returned is NULL NULL about elevation_server HOT 7 CLOSED

Normally server returns NULL for missing data (I forgot to mention it in readme). Did you supply hgt file for this point to make_data?

The file name should be N049E16.hgt

from elevation_server.

Oh I got it now, I am downloading all hgt files, How big is your dem files? Is it too big if we want to support all continents?

from elevation_server.

The collection at viewfinderpanoramas.org is compressed in zip and is about 16 Gb. I think it is about 70-80 Gb when uncompressed.

The resulting data file for elevation server is 19 Gb as it uses lz4 compression.

Thanks, will try to build dem files for all hgt files

from elevation_server.

Thanks @wladich finally got server up with total data, Though there was issue with one file N63E008.hgt, other all files seems to be of size 2.9 MB but this one specifically was 25.9 MB and make_data command was failing after removing this was able to create dem files.

Looks like it was the same problem as in #2 - it is a dem file with 1" resolution but olny 3" is supported
