Hi,
I've imported some rasters by i.in.spotvgt..
I don't understand because the first attempt fail while the second is
ok. Any raster that I try to import, the result is the same. first
attempt=FAIL; second attempt=OK
1° ATTEMPT:
GRASS 6.2.2 (WGS84):~ > i.in.spotvgt
file=/home/alfredo/cartografia/satellite/V1KRNS10__19980521_NDVI__Europe/0001/0001_NDV.HDF
rast=19980521
Import SPOT VGT NDVI map...
A datum name wgs84 (WGS_1984) was specified without transformation parameters.
Note that the GRASS default for wgs84 is towgs84=0.000,0.000,0.000.
Projection of input dataset and current location appear to match.
Proceeding with import...

The problem will be caused by the usage of a pure
number filename. While GRASS generally supports
this, it would need a fix in i.in.spotvgt to avoid that
the r.mapcalc call within the script calculates nonsense...
Quick solution: Just use a letter in output name.
