Obstruction Detection and Data Decimation for Airborne Laser Hydrography

Abstract

Airborne lidar technology is attractive for hydrographic surveying because of its high rate of area coverage coupled will high spatial data density, rapid-response and reconnaissance capabilities, and cost effectiveness. The National Ocean Service (NOS) has been involved in the design, implementation, and testing of such systems in conjunction with NASA, the U.S. Navy, and the U.S. Army Corps of Engineers (USACE) since 1975. Two topics of current interest are 1) the probability of detection of small objects on the sea bottom as a function of their size, and 2) the efficient reduction of the very large data sets to hydrographically representative but much smaller subsets. Results for both of these are reported here.
