Abstract
An approach is provided for regularizing building footprints. The approach, for example, involves designating a vertex of an initial building footprint as an initial vertex of a regularized footprint. The approach also involves generating an edge from the initial vertex to a next vertex of the initial footprint to add to the regularized footprint when that the edge can connect along a taxicab distance. The taxicab distance, for instance, is based on a rectilinear geometry between two points. The approach further involves adding a new vertex to the regularized footprint when the edge cannot connect along the taxicab distance. The edge then connects the initial vertex to the new vertex, and another edge connects the new vertex to the next vertex along the taxicab distance. The approach further involves generating a subsequent new edge or vertex of the regularized footprint for each subsequent next vertex of the initial footprint.
