Chris Macon works for the U.S. Army Corps of Engineers (USACE), Joint Airborne Lidar Bathymetry Technical Center of expertise (JALBTCX). JALBTCX conducts bathymetric and topographic surveys around the world and also supports research and development to advance airborne lidar and coastal mapping technology and applications. He has focused on data fusion processing, product development, and streamlining product generation. His current position is the Technical Lead for the USACE National Coastal Mapping Program.

The U.S. Army Corps of Engineers (USACE) has been advancing the technology used to map the coast for the past 15 years. This is accomplished through the Joint Airborne Lidar Bathymetry Technical Center of eXpertise (JALBTCX). Previous development efforts were largely focused on hardware improvements to achieve increased laser repetition rates and flying speeds. The end goal of these developments were to make airborne lidar bathymetry surveys in a more cost effective manner. The Coastal Zone Mapping and Imaging Lidar (CZMIL) system is the latest development effort by JALBTCX. The goals for CZMIL are not focused around faster collection rates, instead they are aimed at improved system performance over a wider range of water clarity conditions and streamlined state-of-the-art software for data capture, processing, and product generation. These goals are met by a combination of hardware and software advances. The hardware design incorporates the latest and most advanced lasers, receivers, scanners, and imagers. The new sensor improvements utilize a spinning fresnel prism to produce a conical scan pattern with a hybrid flash/scan lidar receiver architecture. The lidar sensor operates simultaneously with a 16 megapixel true color camera and a programmable hyperspectral imager. The data streams allow for data fusion opportunities by being inherently synchronized due to them sharing the same rigid platform and inertial navigation solution. These new opportunities provide high-level information products that address regional physical and environmental concerns which include, but will not be limited to, topographic and bathymetric DEMs, thematic land and seafloor maps, and inherent optical property maps for the water column. This presentation will provide a detailed description of the CZMIL design and the results of the field acceptance test plans which are scheduled to start in August of 2011.
