<P><FONT SIZE=2 FACE="Arial">I would like to know if anyone has attempted to extract morphometric quantities (asymmetry, height, spacing, form factor, sinuosity) from DEMs with sand dunes.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I've developed such code in C before and am about to develop something similar in GRASS but I was wondering if anyone out there has attempted something already in GRASS (I am a new GRASS user).</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Also, are there any routines in GRASS to easily detect topographic edges in GRASS?</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">Thanks in advance for any suggestions,</FONT>
