Clip

This node will clip target geometries to the mask extent. Both layers must be in the same Coordinate Reference System (CRS),otherwise, the CRS of the right table will be transformed to that of the left table. The geometries will be clipped to the full extent of the clip object. If there are multiple polygons in the mask geometry column, the geometries in the target geometry column will be clipped to the total boundary of all mask polygons.

The node is based on the GeoPandas project and uses the following related information and functions:
