I can't remember, and it's on the home system, and I'm at work right
now, but I think it was a s.surf.something masked by a single-value
(0/1) raster made with r.grow.  Very hazy memory there.

I'm afraid I don't quite understand yet what this means, but I know how
to take the r.mapcalcs and script them.  I'll look at what it does,
thanks.

But my question remains, I think ... is the method I used reasonable or
should I be thinking of another method?
