Under this Phase I SBIR, TerraSim, Inc. will develop a novel and robust road network extraction system tailored to the rapid processing of LIDAR data and co-registered reflective and multi-spectral imagery. RoadMAP(tm) from TerraSim, a single image semi-automated road detection and tracking system, will be modified to derive and incorporate height estimates from LIDAR and surface material estimates from multi-spectral data as new and integral components of the road network extraction process.
