Facility Support: A New Two-color Full-waveform Airborne LIDAR System for Advanced 3D Topography and Bathymetric Characterization

该拨款支持为现有的Optech Gemini机载激光条带测绘系统获得倍频光学器件，该系统将使NSF/EAR支持的国家机载激光条带测绘中心（NCALM）首次能够以亚米分辨率绘制非浑浊水域的浅层测深（深度达5米）。传感器头将由Optech制造，并与他们现有的ALSM系统集成，允许在可见绿色光谱下进行水渗透操作。再加上最近获得的全波形数字化系统，NCALM将准备开发双色、全波形光探测和测距（LIDAR）观测技术，包括强度剖面。对浅水河流、湖泊和浅海底栖生物的细微底部地形感兴趣的学术研究人员将首次获得高分辨率的工具，远程水深测绘，规划支持，数据分析和质量控制，以及由NSF支持的NCALM提供的学生研究经验。＊＊＊

0949289 Shrestha This grant supports acquisition of frequency doubling optics for an existing Optech Gemini Airborne Laser Swath Mapping System that will enable the NSF/EAR supported National Center for Airborne Laser Swath Mapping (NCALM) for the first time to map shallow bathymetry (depths of up to 5 m) underlying non turbid waters at sub-meter resolutions. The sensor head will be manufactured by Optech and integrated with their existing ALSM system to allow for operation in the visible green spectrum for water penetration. Coupled with the recent acquisition of a full waveform digitization system, NCALM will be poised to develop techniques for two-color, full-waveform light detection and ranging (LIDAR) observations, including intensity profiles. Academic Researchers interested in the subtle bottom topography of shallow rivers, lakes and the neritic marine benthos will for the first time have access to a tool for high resolution, remote bathymetric mapping together with planning support, data analysis and quality control, and student research experience enabled by NSF support of NCALM. ***
