>David,
I used SURFER years ago to show topology of some small areas. Back then the
file format was a based on a simple x,y,z coordinate system where x=latitude,
y=longitude and z=altitude or some value such as height or amount. These
coordinates were referenced on a general x,y,z=0,0,0 grid. When I was using
this system, I imported it into SURFER from an ASCII text file in columns of
x.
y, and z.
It was all very simple if you had everything as point coordinates.
I have never done this, but you could use v.out.ascii, r.out.ascii or
s.out.ascii. You can
view the manual reference for these commands using g.manual {grass command}.Hope this helps somewhat.

You'll probably want to use r.stats with the -1gz flags to output non-zero
cell values and coordinates as ASCII text. You can pipe this output directly
to awk if you need to modify the format (r.stats also has an option for
defining the field separator character.). Anyway, this will give you x,y, and z
values for each cell. Good luck!
