Hello list,
I have a problem with exporting a DEM to *tif.
There's been quite a lot of discussion on the lists concerning
r.out.gdal to GeoTiffs. See for example [1],[2] and the long thread in
the relevant track ticket[3]. Several of the issues (notably the color
table) have been addressed by recent changes which should be in the 6.4
release candidate. So you might want to try with that.
In a first step I import it via r.in.gdal and in a second step I export
it with r.out.gdal and the file is not the same anymore. GDAL reduce the
file to one pixel but a greater storage size..
As mentioned in [1], block size only seems to be relevant for tiles.
What exactly is the problem ? I mean, except for the fact that the files
are not identical, what is going wrong for you ?
