Hello all, Context: I've loaded some shp files into postgis, containing information over the amazon forest. For reference, the sql script has around 6Gb.
Problem: I managed do import, clean and dissolve properly, but when I run the generalization, by my estimates, it would take almost an year to complete. I also noticed that neither grass nor postgis are capable of parallel processing... Question: Am I using the correct tool for that? Is there a way to speed up the processing? For reference, the commands i've used (grass70, beta4, 22 dez 2014): v.in.ogr -e --verbose input="pg:host=localhost (...)" layer=ap10 output=ap10 snap=1e-6 v.clean -c --verbose input=ap10 output=ap10c tool=bpol,break,rmsa type=line v.dissolve --verbose input=ap10c column=tc_2010 output=ap10d --overwrite Try #1 ) v.generalize --verbose --overwrite input=ap10d output=ap10r method=reduction threshold=0.00025 --overwrite Try #2 ) v.generalize --verbose --overwrite input=ap10d output=ap10g method=douglas threshold=0.00025 --overwrite Thanks in advance and happy holidays F -=--=-=- Fábio Augusto Salve Dias http://sites.google.com/site/fabiodias/ _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
