Urban Terrain Data Availability and Gaps
Jonathan L. Boone, Layton R. Breithaupt, Maria T. Stevens, Benjamin T. Webb, John G. Green, Joshua R. Fairley, and Stephanie J. Price
Real-time urban mobility modeling presents a unique challenge in the area of terrain representation. The terrain must be sufficiently detailed to depict real limitations on vehicle movement, but it must also be transmitted, stored, and processed efficiently enough to allow rapid mobility estimates in a moving vehicle. Moreover, urban environments have different mobility limitations than off-road environments. The primary limitation to mobility in urban areas is expected to be geometry, which includes roadway width, intersection configurations, and overhead restrictions. Additional limits may be caused by static and dynamic obstacles and by bridge capacity limits, which are commonly expressed in terms of Military Load Classification (MLC). Local traffic control measures (e.g., stop signs, traffic lights) may also need to be considered, depending on the desired operation procedures. The goals of this report are to summarize the available baseline geospatial datasets for use in mobility analysis of urban areas and to expose gaps in data availability.
