this depends on http://hub.qgis.org/issues/4955 if you compute areas (with both the filed calculator or the "add geometry columns tool") you get ID Area_FC 25967 8550196769.93 26570 173647473841.47 that makes sense according to the size of polygons > Both results are different than those calculated by R: > > 25967: 9294889613 > 26570: 205414657947 > > Discrepancies with R are particularly large for polygons with area > 1E+10 Can't understand these differences. -- Giovanni -- _______________________________________________ Qgis-developer mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-developer
