[GRASS-user] Region and not-processed data

[stephen sefick]

Where you don't have the image, if I understand you correctly, would
be NULL values?  In that case you will have to default to someone more
experienced, but I suspect that it is run on the entire map, but NULL
means no data so no process.  Just a wag.

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
