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.

BTW: I was able to start something with: python gism.py
Not really functional, though.

Some spare time finally allows me to test the new python gui. I compiled

this is not recognized.
I have python-wxversion, python-glade2 and python-gtk2 installed in my
system. Should I also have something else?
Yes, you need the actual GUI code, which isn’t in CVS but in a
separate subversion repository:
svn co https://grasssvn.itc.it/svn/grassaddons/trunk/grassaddons/gui
It isn’t ready for use yet.
