All,
What is the best way to import elevation data that is in the form
of x and y elevation values in an ascii file?
Is r.in.ascii my best bet? I want to make a binary raster file. I
tried using r.in.ascii but the resultant raster seemed to be a blank
screen. Hmm. Well, any advice would be appreciated.

This has previously happened to me and it took me ages to work out why!
In my case it was because the LOCATION I was in at the time did not cover
the geographical area of the data being imported. In other words grass
displayed the correct layer but it was blank because there was not data in
that area, instead it was displayed somewhere off screen.
So check your region coordinates
