The purpose of this study is to investigate the use of the Defense Mapping Agency Aerospace Center DMAAC digital source data for simulation of Forward Looking Infrared FLIR and Low Light Level Television LLLTV sensor imagery during various periods of the day and seasons of the year. This includes determination of deficiencies of the DMAAC data base which limit its us as well as identification of additional parameters which would increase its utility for sensor simulation. The approach taken in the study was to determine what information is required of the scene, its environment, and the sensor and to generate realistic imagery from it. Then imagery using lesser amounts of data can be generated for various user applications. The impact on the data base can then be assessed for a given application and level of detail in the imagery. The results of this study include a realistic tonal model for the simulation of passive sensor imagery of complex cultural scenes, the generation of imagery from a scene constructed according to the DMAAC specifications, an assessment of the resultant diurnal and seasonal imagery, and the relationship between the model data requirements and the resources of the data base.
