Parcels that actually tile: Avoid Overlaps
· 3 min read
Every surveyor knows the quiet little lie in a hand-digitised parcel layer: the boundaries don't quite line up. Trace a new plot next to an existing one and you either leave a hairline gap or, more often, a sliver of overlap. The overlap gets counted twice, the parcel areas stop adding up, and the "clean" dataset you hand over isn't.
Vertex Snapping got you onto the existing vertices. Avoid Overlaps finishes the job: a topology rule that makes sure the polygon you just drew never overlaps the ones already there - on the phone, in the field, fully offline.
