Hi Frank,
so these are the steps I used on my ubuntu machine:
1. Download the Copernicus Data and unzip
2. create the virtual tif-image gdalbuildvrt all.vrt *.TIF
3. cut the 1°x1° tiles with the perl script
this results in almost 65GB of uncompressed tif tiles
4. convert every tif-tile to hgt us
Hi Steve,
thanks, sounds great.

Hi Franco,
i have seen an silly error in my area. Europa is a little bit greater ;)
Just i have "$lattop = 70". The split create 3608 tif's with 4,5 GB in 85 min.
gdal4hgt create 1171 zipped hgt's with 5,8 GB in 3 h :((
And then i rebuild the tif's from the hgt's in 20 min. That are 4 GB.
