Acquisition of Next Generation Terrestrial Laser Scanning Systems for Community Earth and Polar Science Research

1261653 Mattioli该项目/仪器和设施方案赠款支持购置两台地面激光扫描仪（TLS）和相关的数码摄影设备，这些设备将被纳入目前由五台UNAVCO设施TLS系统组成的共用系统，可供借给更广泛的地球科学界。 TLS系统将支持研究和研究培训，这些研究和研究培训需要有能力在一个约束良好的位置参照系中以高空间分辨率（毫米）迅速绘制地貌、结构和植被的表面地形图。 TLS系统将可用于支持广泛的地球科学和更广泛的应用，包括瞬态表面特征（如滑坡）的研究，屏障海滩过程，地震破裂几何和过程的研究，火山变形，桥梁变形对地球动力过程的响应，海啸产生的地貌和相关特征，冰川地形，地质露头测绘，考古测绘和植物生态学。 这些文书将：1）更换一个老化的、最近退役的TLS系统，该系统最初是在美国宇航局的支持下购买的，用于极地项目部署; 2）用新技术和各种新功能（包括更长距离、全波形数字化和更快的扫描速率）来增强当前的TLS池。 这些系统将通过纳入使用TLS的野外营地演习来支持地球科学教育。 ***

1261653 MattioliThis EAR/Instrumentation and Facilities Program grant supports acquisition of two terrestrial laser scanners (TLS) and associated digital photography equipment to be incorporated into a current pool of five UNAVCO facility TLS system available for loan to the broader geoscience community. The TLS system will support research and research training that requires the capability to rapidly map the surface topography of landforms, structure and vegetation with high spatial resolution (mm) in a well constrained positional reference frame. The TLS systems will be available to support a wide range of geoscience and broader applications including studies of transient surface features (e.g, landslides), barrier beach processes, studies of earthquake rupture geometry and processes; volcanic deformation, bridge deformation in response to dynamic earth processes, tsunami generated landforms and related features, glacier topography, geological outcrop mapping, archaeological mapping and plant ecology. The instruments will: 1) replace an aged and recently retired TLS system originally purchased with support from by OPP for polar project deployments; and 2) augment the current TLS pool with new technologies and a variety of new capabilities including longer range, full waveform digitization and more rapid scanning rates. The systems will support geoscience education through incorporation into field camp exercises using TLS. ***
