Highly Accurate Stereo Satellite Elevation Mapping For Geomorphology, Structural Geology and Project Engineering

Highly accurate stereo satellite elevation mapping is beginning to be used for geomorphology studies, for structural geological interpretation and mapping, and for planning and construction of major oil and gas projects. The use of highly accurate elevation mapping from airborne LiDAR surveys for these applications has been well established for a number of years in southern Canada, the US and Europe. In much of the developing world LiDAR surveying is not practical due to high mobilization and survey costs and/or lengthy aircraft survey permitting processes. Highly accurate stereo satellite elevation mapping is now beginning to fill this role. Several practical applications of highly accurate stereo satellite elevation mapping will be discussed.
