[Qgis-user] Correct the attribute table automatically

[SEGGIE Graeme]

Which version of QGIS are you using? The later ones (certainly 2.12) allows use of a Virtual Attribute. In field calculator – check the box for ‘create virtual field’ and set the correct time to hold geometric area. This should then update itself accordingly.

Regards,

Graeme

hej hej,
at first, I would like to apologize for my english.

I have a shape-file with several areas. In my attribut table, each area has an information about the area size.
Step by step the areas become bigger or smaller. Every time, when this happened, i have to recalculate the area size.  is there a way, that the area size correct automatically in the attribute table, when i change the area?
thanks in advance
josi
