[Qgis-user] Topological editing of two vector layers

[Harish]

If the layers are digitized by different agencies and dissolving is time
consuming for each next higher level, then the automatic snapping of
boundaries within tolerance distance, with keeping one layer as correct
layer will be a useful feature.
