Development of an ESRI ArcToolBox for semi-automated building modeling from multipatch features

This paper briefly describes the development of an ESRI ArcToolBox that leverages commercial-off-the-shelf (COTS) software for the semi-automated generation of Open Geospatial Consortium (OGC) CityGML standard level of detail one (LoD1) and two (LoD2) building models from high resolution imagery and digital elevation models (DEM) for use in blast analysis applications. The ArcToolBox consists of Overwatch Systems Feature Analyst (v4.2), ESRI ArcGIS (v9.2) ModelBuilder, and the Safe Software Feature Manipulation Engine (v2010). This work is part of an on-going project to improve the blast damage predictions and calculation of evacuation distances for explosions in urban environments through development of a fast-running, easy-to-use desktop tool that would combine updated correlation modeling for urban blast and fragmentation with improved semi-automated geometry modeling techniques.
