An automated building detection system has been developed previously based on a line- relation-graph. This paper describes improvements made on this building detection system originally developed for aerial imagery. Major improvement has been achieved by introducing a `super' building hypothesis, which refers to a building hypothesis formed from a `U'-shaped chain of lines. This paper also reports experiments on automated building detection from 2 m resolution spaceborne imagery (DD5) using the improved system. Although small buildings could not be extracted (as they were not visible), the improved system showed strong feasibilities of (fully) automated extraction of large buildings from DD5 imagery.
