 Modeling Buildings for Mission Rehearsals Track: Defense and Intelligence Author(s): Stuart Blundell, David Opitz, Chris Finlayson The modeling of building footprints, heights, and roof shapes is critical to U.S. Defense Department mission rehearsal since buildings dominate and characterize urban landscapes. The purpose of this paper is to present a new approach for creating models of buildings and their geometry from elevation data. For this study, vector representations of buildings are created by applying concepts based on a novel machine learning approach that incorporates spatial context in the modeling process. Accuracies of the building count and of selected building geometry in the test area are assessed by comparison with real-world reference data. Software performance is measured and reported by comparison with traditional techniques. Finally, the models are automatically simplified and incorporated into the 3D Analyst extension for the purpose of mission-specific rehearsal.
