This question already has an answer here:
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.
Please let me know how to calculate the intersect two shapefiles.
Thank you in advance.
I used "Field Calculator" to calculate the intersection with $area. But those numbers are bigger than original area.
