I have merged two vectors layers. When I try to merge two features -
originally from two different source layers, now in the
Merged layer - I get this error:
Layer Merged: Geometry type MultiPolygon not compatible with provider type Polygon.
I'm not sure how to solve this.
1) To begin with, how can I successfully merge two layers if they have different geometry types?
2) In my case, how to understand which source layer is considered by QGIS as a MultiPolygon and which on is a Polygon. In their
Properties -> Metadata -> Properties -> Geometry type of the features in this layer
they both appear as
Polygon (WKB type: "Polygon").
3) How to manipulate the layers so to successfully merged features from the two source layers?
