[OSGeo-UK] QGIS query

[Al Graham]

Hi all
A (hopefully) quick QGIS question for you.

If I am digitising land cover from an aerial photo is there a way to limit
the size of the polygon geometry to a minimum mappable unit (MMU)? For
instance, say that size is 3 square metres, is it possible for QGIS to
automatically flag, or reject, a new polygon that is 1m by 1m? Or is this
something I would have to reconcile once the digitising has been completed?

I think it's the latter option, but I thought I'd ask in case there's some
special QGIS function I am unaware of.

Cheers
Al
