[GRASS-user] v.surf.rst

[Amaginary Studios]

Hello,

I have been toying with creating 3D surfaces from my vector data  
(contour lines) matched to my AirPhotos out of interest.

My vector file has a category "ELEVATION" with all the z values in  
meters.

Now, when I try to run v.surf.rst I receive this output:

DBMI-Postgres driver error:
Cannot select:
SELECT cat, ELEVATION FROM w0124.contour
ERROR:  column "cat" does not exist
LINE 1: SELECT cat, ELEVATION FROM w0124.contour
                ^


Reading lines from vector map ...
Database record for cat 1 not found
.....

It is true I do not have this column "cat" in my w0124.contour table.

I am interested in understanding what this column "cat" is used for  
and some more information on how I should be addressing this issue.

Thank you.

Mars
