[Gvsig_english] Calculating areas in the atribute table.

Mon Jan 28 10:18:33 CET 2008

I agree that an option to manually correct individual labels would be great. I remember old AV 3.2 having an extension were you could export labels into a shapefile, which gives you even more options for later corrections.

Regards,
Wolfgang
