Hi,
How would GRASS best answer a question like:"Show me all areas that are 5 miles from site A?"
-OR-
"What areas are 50 meters from highway C AND have a slope of 3-5 degrees?"Assuming I already know the terrain characteristics, what is the best method
for asking GRASS this question? I was thinking of some sort of proximity
function, but I've found nothing in the manual so far.Any suggestions would be greatly appreciated,
Dianne
Maybe this will work....
g.region map= "site.rast"
r.buffer input=site.rast output=site.buff (with proper params. of 50m)
r.cats site.buff (what cat# is 50m?)
r.reclass slope (slopes of 3-5 deg. equal to 1)
r.mapcalc answer = if((site.buff == "cat#") && slope.reclass)
I'm sure there must be a faster way, but I think this will work....
Don't flame me if not though.
