I have two shapefiles.
1. the clinic buffers 500m area.
2. the postcode area.
Is there a simple way to calculate the intersect two shapefiles ?
I'm using QGIS Dufour. I tried to use fTools to intersect. However, it didn't show me actually how much every piece of the green area. It just combined the fields of two shapefiles.
How do I calculate the intersect of two shapefiles?
I used "Field Calculator" to calculate the intersection with $area. But those numbers are bigger than original area.
