TerraSim software solutions are used in three major market segments, each sharing the common requirement of rapid production of 3D visualizations from heterogeneous user data. Defense modeling and simulation, site modeling and intelligence database preparation, and civil applications including city and regional planning, represent unique markets for TerraSim's products and services. The power of the TerraTools Core approach is to support the advanced processing of cartographic vector data, 3D object models, and remotely sensed imagery compiled into highly accurate real world environments.

TerraSim introduced the first commercial use of integrated triangulated irregular networks (ITINs) in 1996 which has since been adopted as the industry standard terrain representation for high fidelity 3D geospatial visualizations and as the underlying representation for large area modeling and simulation databases. Advanced database construction tools include processing of cartographic features into the TerraSim ITIN representation as well as "just enough GIS" to support feature correction, merging, buffering, and attribution processing.

TerraTools users can customize their software by adding application-specific plug-ins that fully inter-operate with Core processing. Typical TerraTools configurations are described in the following market segment descriptions. However, our product offerings can be mixed and matched to provide our customers with the lowest cost solution that best addresses their application requirements.
