Dear OSGeo users,
 

Thanks in advance.
 
I need your assistance to work with the above data set. I have installed this data set from http://casoilresource.lawr.ucdavis.edu/drupal/node/438. This is a winzip file and I have extracted all files into the directory \speafish60 directory. The files structure after extraction is like this:
 
- \speafish60\PERMANANENT
  - \speafish60\PERMANANENT\bdlg
  - \speafish60\PERMANANENT\cats
  - \speafish60\PERMANANENT\cell
  - and so on
- \speafish60\user1
 
I have installed R-2.10.1 on windows XP.
 
I have installed http://trac.osgeo.org/osgeo4w/.
 
I am able to interact with GRASS and R.
 
# set region in GRASS
 
g.region rast=elevation.dem
 
I have issued this command at Cmd > at GRASS GIS Layer Manager Window.
 
But I have received the error below: 
 
ERROR: Raster map <elevation.dem> not found
 
How can I change the directory name in GRASS to access the data.
 
Once again, thank you very much for the time you have given.
 
I am looking forward for your reply.
 
Regards,

 
Deb
