I just encountered the problem that my colleagues can't import data exported
from GRASS appropriately into ArcView.
I tried to convince them to use GRASS but without success so far ,-)
the raster to export specs are:
Type of Map: raster Number of Categories: 255
Data Type: DCELL
Rows: 2230
Columns: 3434
Total Cells: 7657820
Range of data: min = 0.000000 max = 35.653061
r.out.tiff input=test output=test -t //results in 3 bands in ArcView not in
one; from ERDAS I know that I can specify if 1 or 3 (RGB) bands shall be
exported
r.out.arc input=test output=- > test.grd //results in no image at all
r.out.ascii does not import as well.
I recognised missing endings of the exported files. Do I have to add certain
file specifications?
Any experience with GRASS -> ArcView communication?
regards, Martin

Martin, have you tried r.out.bin? Also, when using r.out.ascii, did you specify the number of significant digits with dp=? I might be wrong, but I don't think tiff supports decimal values. I am not sure about the r.out.arc, i haven't really used it before.

What about r.out.gdal? It will give you several options, many of which are supported by ArcView. I haven't used this module, but have used GDAL extensively. You may even be able to just use gdal_translate (part of http://fwtools.maptools.org) to convert GRASS raster straight to TIFF with less headache.
