Abstract

Generation and representation of synthetic environments is a key factor in using a simulation system for the particular application it is designed for. Realtime networked simulation places additional constraints on the successful creation of these environments. When these networked simulators operate in close proximity to the ground, the constraints on the synthetic database become even more stringent. This paper describes some of the challenges associated with the creation and usage of these synthetic databases for ground and near-ground applications in a networked simulation system. The representation of the information for the same terrain region can be drastically different based on the needs of a simulation platform, or the specific application. The paper touches on these diverse computing needs and on how they affect the creation and exchange of a synthetic terrain database in a networked heterogeneous system. For example, creation of electronic or paper maps demands a data representation scheme that may not be suitable for a thermal sight simulator, even though they are both intended to depict and operate in the same geographical region. The key steps in creating synthetic databases are reviewed and the trade-offs in source data selection, geometric representations, and issues such as interchange and interoperability are highlighted. Some management considerations in improving the process, quality, and tool development are also discussed.
