I am currently in the process of qualifying some polygon data in QGIS. Specifically, I have to ensure polygons from layer 1 follow the edges of the polygons in layer 2. Sometimes, copying the geometry of a polygon from layer 2 is more useful than manually editing the polygon in layer 1.
This is where my question arises; is there anyway to update the geometry of a polygon in layer 1 to match that of a polygon in layer 2? I want to keep my original data, only updating the geometry.
I am manually editing a polygon layer in QGIS, so no automation is necessary. I am the only one involved in the project.
The other polygon layer I have consists of smaller polygons that should be combined to form polygons for the other layer, whilst preserving the attributes of the original layer.
Hope this makes sense.
I can also work in PostGIS, if that makes my problem easier to solve.
I have tried the using St_Snap and Topology Checker, however I have not been able to solve my issue using these.
