resampling grid_data

[martijn at scanner.frw.uva.nl]

Hi Daniel,

cells with 0's are `no data' in Grass. You can't get rid of them, except 
by finding data to replace the 0's. You CAN disregard the 0's, either 
visually (display the map with the -o flag) or during analysis (by 
aplying a mask). From you question it is not entirely clear what you mean.
