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

[Benjamin Ducke]

Are you sure you have the right extents?
Try

 g.region rast=puertoRico

then display again. Also, you could try:

 r.info puertoRico

to get the raster statistics and extent and check
if it makes sense.

Are you on Windows?
The output below shows that the map is being written
to a PNG output file. Did you check that file?

Cheers,

Ben
