Obtaining areas from overlapping polygons

Obtaining areas from overlapping polygons


Using ArcView 9. I have a data set of about ten thousand parcel polygons and a similar number of driveway polygons extending from a roadway polygon into the parcel polygons. My ultimate goal is to get the driveway area within each parcel. Ideally this could be done through the creation of a new shapefile so that I can have a concise plan for each parcel, but any method that works is welcome.


Sounds like you need to use the Interesct tool. This will output a new SHP file of driveways that overlap your land parcels along with the attributes of both datasets.

You can then add a new field to this outout dataset and calculate the geometry of each polygon to give you the area of driveway. Assuming each land parcel has a unique ID you can then join this intersect area back to your original Parcel dataset then allowing you to work out how much of each land parcel is driveway.
