Claim:
1. A method for extracting a building footprint from imagery data, comprising: accessing imagery data of land containing a plurality of parcels; detecting with a processing circuit image contrasts between natural terrain and potential man-made structures in said imagery data; determining a parcel from the plurality of parcels that a portion of the potential man-made structures are located on by overlaying parcel boundaries over said imagery data so as to spatially distinguish said plurality of parcels; and extracting a building footprint of a detected man-made structure on said determined parcel from the plurality of parcels that the portion of the potential man-made structures are located on, said extracting including filtering-out remaining potential man-made structures having features inconsistent with predetermined extraction rules defined based at least in part on property characteristics for the determined parcel from the plurality of parcels that the portion of the potential man-made structures are located on.
