Hi, I try to calculate area with ftools add geometry column. I have noted that in automatic new field “AREA” have this properties type=real lenght=10 precision=6, this involve an error, some numbers are lost, because the Area number have lenght>10. Example: if I calculate Piedmont area with Ftools obtain 2539107283 if I calculate the same Area , add new column (type real lenght=20 precision=5) and use calc field ($area) I obtain 25391072834.9971.
Sorry for my english, I hope you undestand me and the error. Regards Enrico _______________________________________________ Qgis-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/qgis-user
