I tried to import USGS' (2011) Global Mangroves map: # stuff copied from the map's *latest* history v.in.ogr dsn="/geo/geodata/mangroves/usgs_mangroves/usgs_mangroves2.shp" output="global_mangroves_usgs_2011" min_area=0.0001 snap=0.000000000000001 2018421 input polygons Total area: 1.47005E+11 (2750605 areas) Overlapping area: 5.32085E+09 (41540 areas) Area without category: 9.25489E+09 (773734 areas) Twice the "error" message was like (even after I, by mistake, imported with snap=1e-15): Ended with an "error while impoting, try to import with snap 1e-14" This means that there are still errors in the map, right?
