Did you ever have a look at the compiler

I'm supportive of that, starting with trunk. (too
late for 6.4.2) r.los just doesn't scale.
still one final small detail with the color rules
I'd like to see:

It requires knowing the
+1 from me, looking forward to using r.viewshed on some massive maps-
would be nice to have it in the standard install of GRASS.

basically it is faster and it scales to large regions well.
I don't know the exact O()ness level of it, but r.los becomes very quickly
slower after the region size gets bigger than a smallish amount of rows x
columns, to the point where it

Thanks. If r.viewshed is fast enough, a Python script could be built that uses
r.viewshed to replicate many of the aspects of r.cva.
