Hello,

I have tried to send part of this message before but I assume it did not
reach the list due to list-related problems, apologies if you have
received this before.

A colleague of mine is attempting to solve a problem that I'm hoping
users of GRASS may be able to help with.

My colleague is looking for software that will characterise the
complexity of the boundary of an area. That is, if the boundary of an
area had very `wiggledy' complex edges then it would be distinct from an
area of which the edges were very smooth. The ultimate aim is to
describe and compare the shape of different boundaries of enclosed areas
derived from an interpretation of remotely-sensed imagery. 
 
I assume that a fractal-based approach would be a viable way to approach
this problem. I am wondering, therefore, if anyone is aware of any GRASS
programs, or indeed other software, that might be suitable for this purpose.

Also, has anyone heard of a GRASS module called r.le? Apprently, it is
used to quantify landscape metrics. If anyone could suggest where it
might be obtained I would apreciate the relevant information. Please
could you send any replies to my email address as well as to the list.

Thanks in advance,
 
Chris Lloyd
