Dear Grass Users,
My question is simple and fundamental. I intend to import shapefiles into grass and clean them and then export them back. The shapefiles may have topological problems like overlapping adjacent polygons, gap between the polygons etc. I know in grass we can import shapefiles using v.in.ogr and then do a more rigorous cleaning using v.clean but I am not sure as to which combination of tools to use in v.clean and in what optimal order!! All my attempts so far has led to erroneous results. Can anyone suggest an optimal scheme of doing topological correction in grass and what thresholds to use for these different tools withing v.clean? My shapefiles have linear units in meters.
Any help will be appreciated.
Regards
