Hello,<br><br>I have a raster file created in R using the gstat package and already exported this raster elevation file in GRASS.<br>I would like to know how to compute the adirectional slopes of this raster. Meaning of adirectional slope is the maximum slope in a region (i.e 3x3 neighborhood around each cell in the elevation file). Can I do that using GRASS? Is it what the function "r.slope.aspect" does, maximum slope in the region? Can I set the size of the windows, 3x3 or 5x5 etc...? <br>Thank you very much for your reply.<br><br>Regards,<br><br>Javier.<br> <br /><hr />Disfruta antes que nadie del nuevo <a href='http://download.live.com' target='_new'>Windows Live Messenger</a></body>
