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

1261653 mattiolieear /仪器和设施方案赠款用于购置两台地面激光扫描仪（TLS）和相关的数码摄影设备，这些设备将并入联安援助团现有的五台设备TLS系统，供更广泛的地球科学界使用。TLS系统将支持研究和研究培训，这些研究和培训需要能够在良好约束的位置参考框架内以高空间分辨率（mm）快速绘制地形、结构和植被的表面地形。TLS系统将可用于支持广泛的地球科学和更广泛的应用，包括瞬态地表特征（例如，滑坡）的研究、屏障海滩过程、地震破裂几何形状和过程的研究；火山变形、桥梁变形对地球动力过程的响应、海啸产生的地貌及相关特征、冰川地形、地质露头填图、考古填图和植物生态学。这些仪器将：1)取代老旧的TLS系统，该系统最初是OPP为极地项目部署购买的，并得到了OPP的支持；2)利用新技术和各种新功能（包括更远的范围、全波形数字化和更快的扫描速率）增强当前的TLS池。该系统将通过使用TLS整合到野外营地练习中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. ***
