roads intersecting with canopy gaps

Discussion created by tili on Oct 11, 2012
Dear all,
I am facing following problem:
Gaps that I calculated from a nDSM are partly forest roads. As the roads by definition are not gaps, I am looking for a way to identify them.
There is no road shape file that I could use, because it´s very poor digitized and often beside the true position.
I was thinking of a linearity index, because the main part of the  identified road pixels road are elongated in shape.
I found the linearity index in the Help of FragStats but I could not find it in the program. I am not familiar with fragstats???
If anyone out there could assist me with that or could think of any other way to get rid of these road pixels, I would be very happy.

Greetings, Michaela
