Paper Abstract

Foliage penetration is a major application of airborne lidar systems. Typical ground resolutions achieved for floodplain-mapping applications are of the order of meters. Much higher ground resolution can be achieved by integrating multiple looks from several look-angles. This paper describes a new system that can achieve very high ground sampling densities in forested environments at significant altitudes (6 kft) using a modified commercial lidar and a custom gimbal system. Absolute calibration of the gimbal system demonstrated pointing knowledge comparable to the usual aircraft-fixed lidar performance (0.1-0.2 mrad). Bare-earth processing of the resultant data enables interactive virtual deforestation relative to a high-resolution ground.
