Hello,
I am trying to r.in.gdal to import an Eosat Fast formatted Landsat image
into GRASS 6.1 (running on SUSE Linux 10.1). It requires pointing to the
dataset header file as input, and specification of the band that is to
be imported. I get the error message:
Input map is rotated - cannot import. You may use 'gdalwarp' to
transform the map to North-up.
I have looked into the documentation of gdalwarp, but it is not clear to
me how I go about rotating the image to North-up. Does anyone have
experience with the parameters/arguments necessary to transform the
image using gdalwarp before import into GRASS?
Thanks, Bill

It is pretty straight-forward:
gdalwarp rotated.tif northup.tif
That's (usually) it - you may optimize with some gdalwarp parameters.
The newer manuals mention this:
"Error Messages"
"ERROR: Input map is rotated - cannot import." ..

Hope this helps,
