You can extract the geometry from feature polygon and point and you perform a geometry intersection.
Here is a sample in python. featurePolygon - pointer to feature polygon featurePoint - pointer to feature point polygonGeometry = featurePolygon.geometry() pointGeometry = featurePoint.geometry() if featurePolygon ["ID"] == featurePoint["ID"] and pointGeometry.intersect(polygonGeometry): #Do whatever you need to do. print pointGeometry.intersection(polygonGeometry) Marian -----Original Message----- From: Qgis-user [mailto:qgis-user-boun...@lists.osgeo.org] On Behalf Of sinorfavela Sent: May-17-17 8:03 AM To: qgis-user@lists.osgeo.org Subject: [Qgis-user] Check intersection of polygons and points with same value in ID field. Hi there! I need to check if the features of a polygon shape intersect with the features of a points shape with share the same value in their ID field. In other word, if the polygon with ID "54" intersect with the point with ID "54" and so on with all the features. ¿Any idea? I guess that could probably made with the field calculator, but I cannot figure out how to build it.
