which gdal steps

[joerg pfeiffer]

Frank,

thanks for your answer, but I have a problem:

 > gdalwarp in.tif latlong.tif -t_srs WGS84 -co TILED=YES

I did
gdalwarp in.tif latlong.tif -t_srs WGS84 -co TILED=YES -rc

After this, I opened the image again in globalmapper. The reprojection
was fine, but now the image is somehow destroyed. It looks like a
pointilism image, lots of very little colored areas, almost like points..

Was this the -rc option, or is the problem before that?

Joerg
