Dear listers,

I am exploring r.le and r.li, but I am afraid those two sets of programmes are providing what I need only partly. Before using them for shape and diversity analysis, I just would like to get the number of pixels (or the area) by attributes types (eg the attribute is a class of CORINE landcover or any classified image) in each sampling unit into a text file. Sampling units would be circles of a given radius centered over sites (overlayed on the raste to analyse). I can provide either a vector file with the center points or imported polygon shapefiles. Surprisingly it seems that this simple statistics is not provided in r.le (maybe wrong ?). I suppose this may be due to the fact there is a much more simple way to do it in GRASS, but cannot find it in Neteler and Mitasova book.

Any hint welcome,

Patrick
