Abstract

A method, apparatus and computer program product are provided for extracting building footprints for buildings based on satellite imagery. In this regard, a segmentation map is generated by performing an image segmentation on satellite imagery depicting at least one building. A plurality of line segments that correspond to edges of the at least one building are also generated. Furthermore, a contour for each of the at least one building is generated by filtering line segments corresponding to the at least one building based on the respective principle direction. The geographic data for each of the at least one building is then extracted based on the respective contour.
