Abstract:

Terrain modeling and visualization is emerging as a key requirement for tactical mission planning, rehearsal, and battle management systems. This study assesses the match between commercial superworkstation computers and the needs of deployable, unit level systems for these applications. Superworkstations are shown to be functionally well suited to terrain visualization. A prototype terrain visualization system, hosted on a Silicon Graphics IRIS 4D240GTX workstation is discussed. This prototype demonstrates the concepts developed in this study by exhibiting features such as an out-the- window perspective terrain scene synthesized from Defense Mapping Agency DMA databases, Landsat images inset into the geometric terrain model, head-up display HUD simulation, radar detection envelope representation, haze effects, lighting effects based on time of day and date, and a Gods eye-view viewport display. Finally, topics for continued investigation into superworkstation and terrain visualization are covered.
