Hi, I try to import a 1GB Shapefile and the geometries seem to be in a really bad condition. Building topology GRASS exits after 30 hours with an OUT OF MEMORY! error (see below).
Can someone give me hint, what I could do, to import this file? Using -c or -f flag is no option, because I would like to use GRASS to clean the data as far as possible automatically and I wouldn't like to split the file into subregion, if I don't have to. The PC I use is a dual core 1,8MHz with 4GB RAM and 1.6GB swap. Is this still not enough or can I change something in GRASS (extend or change memory parameter) to finish the import? I used a svn version from yesterday. below you see parts of the 230MB log file: thanks Otto ############# part of logfile Projection of input dataset and current location appear to match Layer: schutzgebiete Importiere 886619 Objekte der Karte...
