The feature content requirements for terrain databases used in the Modeling and Simulation industry continue to grow. The requested database geographic extents are expanding. Database feature densities and complexities are increasing. New simulation systems are leveraging game engines, enabling this growth in database content requirements. Unfortunately, the cost of producing 3D cultural models, that reflect these increased complexities, using traditional commercial 3D modeling tools, by hand, is quickly becoming unsustainable, and maintaining and updating 3D cultural models libraries are becoming unaffordable. The process of assigning 3D model references to vector features in a geospatial database, identified as modelization, has been automated by the SE Core program to significantly reduce database production costs, improve database quality and consistency and increase run-time database performance. This paper describes the processes and tools used in the Automated Modelization Process in the production of the Synthetic Environment Core (SE Core) terrain databases. When applied, these tools and processes results in a cost effective approach to automatically generate 3D cultural models that are designed for the specified run-time requirements, saving considerable development time when compared to using commercial 3D modeling tools and manual processes.
