Abstract: Procedures are being developed for computer generation of thermal images that depict realistic landscape perspective and are radiometrically correct. Digital three-dimensional (3-D) representations of thermal terrain conditions can be used for software and hardware in the loop testing by weapons system designers, developers, and evaluators. The procedure has four components: (a) environmental information bases that characterize the static and dynamic aspects of the landscape, (b) physics-based numerical thermal prediction models, (c) radiance prediction models, and (d) computer graphics system for generating a 3-D thermal landscape perspective. This report describes the information base content, structure, and analysis methods developed to store and access 3-D terrain, weather, physical, thermal, and spectral property data required to support all procedure components. Methods for characterizing and quantifying environmental information as a 3-D dynamic landscape; formatting, managing, and retrieving diverse environmental information for numerical modeling purposes; and analyzing terrain data are discussed. The spatial elements of the landscape are configured in a geographic information system and define the 3-D aspects of the environment. Physical, spectral, and thermal properties of the spatial elements are configured in a relational database management system integrated with the geographic information system.
