No subject

that the (conceptually at least) easiest thing to do is to alter r.recode to
accept input (stdin or text file) in the form of

x1,y1,val1
x2,y2,val2

or even better, if we want to keep a similar format to that now used for cat
value recoding

x1:x2:y1:y2 val1
x3:x4:y3:y4 val2

where x1:x2 defines a range of x coordinates and y1:y2 defines a range of y
coordinates. This way single cells or blocks of cells could be referenced
and changed. This mode would probably open up a number of new modeling
possibilities within GRASS too.

This mode could be controlled by a flag. What do you all think? Is this
feasible? Is it fairly easy or fairly difficult? Is there a better way to
change a group of cell values based on their xy coordinates?

Thanks for your input.
