Re: [GRASS-user] r.watershed error

Thanks Markus, Let me make sure I understand. For best results I need to set the resolution to 10m for the 1/3 arcsec. With the region set as it is (most of Northern New England) when I do this I run out of memory. To over come this, I can set the region to just encompass just the NED13_01 s

Hi, I'm using the shapefile of the GADM database of Global Administrative Areas (http://www.gadm.org), but the subdivisions of some countries (such as Spain, Slovenia and others) are too small. In order to get divisions that are more evenly sized among all countries, I need to dissolve sub-regions
