Rapid statistics for subareas of a raster map?

Download a program called FRAGSTATS. I do not know the net site, but
it has been developed by K.McGarigal and Barbara Marks of the Forest
Science DEpartment, Corvallis, Oregon State University. They make it
available free on their net site.
It is really good. Takes in input in 6 standard formats, including IDRISI
and ERDAS, and outputs all kinds of patch, class and landscape statistics.
It has an option to mark each patch with a unique ID no, which you can
later use to pull out the statistics you want. You could use it for all
patches in a landscape, or all patches belonging to a single type, too,
and it gives you summary statistics for them. It's a small package, fast
to download and easy to use. I used it for all my thesis work.....

Hope this helps.
