Building footprint extraction apparatus, method and computer program product

Abstract

A system, method and computer program product cooperate to extract a building footprint from other data associated with a property. Imagery data of real property is input to a computing device, the imagery data containing a plurality of parcels. A processing circuit detects contrasts of candidate man-made structures on a parcel of the plurality of parcels. The candidate man-made structures are then associated with the parcel. A building footprint is then extracted by distinguishing a man-made structure on said parcel from natural terrain, recognizing that man-made structures when viewed from above generally show a strong contrast from background terrain. Remaining candidate man-made structures are removed by observing that they having features inconsistent with predetermined extraction logic.

1 . A method for extracting a building footprint from imagery data, comprising:
 inputting imagery data of land containing a plurality of parcels;   detecting with a processing circuit image contrasts between natural terrain and potential man-made structures on a parcel of said plurality of parcels;   associating the potential man-made structures with the parcel; and   extracting a building footprint of a detected man-made structure on said parcel, said extracting including filtering-out remaining potential man-made structures having features inconsistent with predetermined extraction rules.
