Hello, I'm having some trouble with r.horizon. I've got a very big DEM, and I keep running out of memory. After some experiments, I think the options bufferzone and maxdistance may be part of the problem. It isn't listed in the help file what the units for these are.
I'm preparing maps for use in r.sun, and the example in the r.horizon help page suggests I use bufferzone=200 and maxdistance=2000. Does this mean meters? units from the map projection (which are degrees)? Omitting these parameters I can complete an analysis in a minute or so, when including them produces a crash sometime after the process consumes all my RAM and swap memory. Thanks for any clarifications! -- Tyler Smith ty...@plantarum.ca _______________________________________________ grass-user mailing list grass-user@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/grass-user
