[Qgis-user] Field Calculator calculates negative area

[magerlin]

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.
