Dear All,
I've imported a .PNG file with r.in.gdal (i.e. map.png) in order to make a
georeferencing file. The importing procedure returned 3 files: map.red,
map.green, map.blue. I don't know how continue to reach my goal.
Thanks in advance

Hello all
have problem with exporting grass-vector-areas to shape-file
I suppost an area is a closed boundary with a centroide inside (v.digit

Dear MODIS-experts,
I attempted to de-stripe a MODIS band 5 (periodic striping) with FFT and
manual masking in the frequency domain (as explained in Introductory
Digital Image Processing, Jensen & the 2nd GRASS-book, Neteler &
Mitasova).
I am not really satisfied with my results. Is there another

See the man page, it has examples.
If that does not help, it might be easier if you sent us your sql file

I'm trying to import a PostGIS table in GRASS by v.in.ogr.

importation works well and I have a correct GRASS vector but if I look

Dear list,
I've a problem when I export a map with r.out.gdal format=GTiff

When I open the exported map in QGIS it appears null values where it

Someone know how to solve this?
Thanks very much.

I have two datasets, both with about 1 million points per dataset (lets

closest point in B is (e.g. a spatial join). I can (and am) doing this
