Hi Lene I am aware that the polygons not are topological OK - I've tried to use Grass to clean them but had no luck.
But anyhow I think Qgus should be able to calculate the areas - I could have been in a situation where overlapping polygons were OK. As can be from the other correspondance it seems to come from a 10 digit limitation on integers. ----- Regards Morten Qgis 1.8.0 Stand alone installer in Win7 64 bit -- View this message in context: http://osgeo-org.1560.n6.nabble.com/Field-Calculator-calculates-negative-area-tp5042754p5042771.html Sent from the Quantum GIS - User mailing list archive at Nabble.com. _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
