[GRASS-user] I need some help to import a GIS file to GRASS64

[Ivan Henriquez Rivera]

Hello!

My name is Ivan.
I have been trying to import a GIS raster flie to GRASS64.
I do the next proucedure in Ubuntu 10.04:

-I run grass64
-I define a new location using the EPSG code: 32161 (based in the
information at the end of this email)
-When Grass asks me: Select datum transformation parameters,
 I choose the second one: (Used in whole nad83 region. towgs84 = 0.000,
0.000, 0.000)
-Then I enter in the PERMANENT folder.

And then I do this:

r.in.gdal input=/home/ivan/grassdata/prgap_landcover.img output=puertoRico
Projection of input dataset and current location appear to match
r.in.gdal complete. Raster map <puertoRico> created.
d.rast map=puertoRico at PERMANENT -o

The problem is that the Map Display is in blank.

If you want to try it, you can donwload the file from
ftp://ftp.gap.uidaho.edu/products/Puerto_Rico/GISdata/Landcover/1_Land_cover_grid/
the file is prgap_landcover.zip<ftp://ftp.gap.uidaho.edu/products/Puerto_Rico/GISdata/Landcover/1_Land_cover_grid/prgap_landcover.zip>,
and inside you will find the a .img file
