[GRASSLIST:8118] RE: v.surf.rast

[Tom Colson]

I don't have Grass running... But try it using the CLI (command line
interface, which you should know how to use anyway). The GUI, in my personal
opinion, isn't always the ideal method for running tools. 

When you do it via the CLI, cut 'n paste that command, but drop
zcolumn=c2cont. Layer=1 should pick up the z col automagically. If that
doesn't work, COPY your layer and rename the c2cont field to z.
