I have a contour line file that covers the most part of north italy (shape is 0,6 gb) and I want to use v.generalize (snakes algorithm) on it. Because of the large file size, if I use Grass 6.4.3 I saturate all my memory and after 1,5 days of work nothing appends (the progress bar does not increase). I tried to use Grass 7.0 and I got this error "ERROR: G_calloc: impossibile allocare 11777 * 8 bytes di memoria a matrix.c:37"
For a good generalization I can't devide the layer... Someone have a suggestion for doing that?
Thanks in advance.
