I have a shapefile containing points that I want to make into a voronoi diagram. I import the shapefile into GRASS and then run v.voronoi, but I then get this error...
C:\Program Files (x86)\Quantum GIS Wroclaw>v.voronoi --o input=pass1@mapset1 output=pass2 Reading sites... Voronoi triangulation... Building topology for vector map <pass2>... Registering primitives... ERROR: G_realloc: unable to allocate 15348004 bytes at struct_alloc.c:133 Its quite a big file (1.5 million points, GRASS database file is 368MB, vector files total 112MB) so maybe its not a bug but what I'm trying to do is just too big (I read somewhere about a 2GByte limit for 32-bit apps or something like that). The thing is I'm kind of stuck as I cant think how you could make a voronoi diagram by splitting the source into smaller files and trying to join them up again. What is GRASS's memory limit? Should I get more RAM? Would using Linux instead of Windows help. Can anyone think of things I can experiment with to reduce the amount of memory used? I'm on Windows7 64 bit, 4GB RAM, GRASS 6.4.250870M (2012) Thanks. -- View this message in context: http://osgeo-org.1560.n6.nabble.com/G-realloc-error-with-v-voronoi-tp4634231p4634231.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
