Terrain Analysis Program - The highly variable nature of terrain (e.g. topography, ground/vegetation cover, soil type) can greatly impact global military operations. Mission success, including operational mobility, weapon performance, communications, and counter IED/landmine, all depend on accurate knowledge of terrain conditions. Unfortunately, accurate terrain data in areas of strategic interest is commonly limited or inaccurate. DRI developed the Terrain Analysis Program (TAP) to advance technology to provide prompt and accurate characterization of all terrain types and conditions using a combination of space- and airborne- information and science-expert analysis. The objective of TAP is to provide customer focused, science-based knowledge of terrain conditions tailored to specific military issues and challenges.
