Hello everyone,
I have to do some work on a 7.5 minutes DEM. Does anyone know how to extract
or calculate ridges, valleys, drainage divide, drainage channels, slope
curvature and slope shape ? And where can I get the book "r.mapcalc: An
algebra for GIS and Image Processing" by M. Shapiro and J. Westervelt?Thank you in advance.
