[mkgmap-dev] DEM-file generation from geo-tiff sources ?

Thu Jan 4 20:59:34 GMT 2018

Hi Frank,

thanks for the new hints, this sounds much simpler than my approach.

Especially the "virtual" tif-File should save a lot of time and disk space.

But anyway there will be more than 1000 tiles for all the copernicus data.
1000 times a few seconds - it's still over one hour. But converting 37GB of
data just takes it's time.

for the last step you use your own program. Is it faster than gdal_translate
?
 "gdal_translate -strict -q -eco -of SRTMHGT -outsize 3601 3601 "  should 
basically do the same job, right?

Ciao,
  Franco
