Community Workshop: Charting the Future of Terrestrial Laser Scanning (TLS) in the Earth Sciences and Related Fields

这笔赠款支持一个社区研讨会，以确定陆地激光扫描(TLS)应用的战略方向，以快速绘制自然和人造地物的高分辨率表面图，以及地球科学界如何最好地实现对该技术的支持。TLS是以光探测和测距(激光测距)技术为基础的，能够以厘米到亚厘米的分辨率绘制表面图，应用于绘制断层崖、地质露头、火山特征、冰川特征、障碍滩地形、流域排水特征、森林树冠和植被覆盖以及土木结构的地图。与全球定位系统参考位置相结合的重复TLS调查，使得能够对地表变形进行细微变化检测，以响应活动构造、气候变化和极端事件以及活火山活动。存在远距离TLS能力，可以绘制出1-2公里的表面，从而为使用更传统的绘制技术快速绘制可能对人类构成危害的特征提供了优势。高分辨率TLS测绘补充了星载和地面雷达和激光雷达测绘模式，用于需要厘米到亚厘米表面分析的研究。计划于2011年10月下旬在科罗拉多州博尔德举办为期三天的研讨会，约50名具有利用TLS促进地球系统过程理解的经验和兴趣的地球科学家和学生将聚集在一起。组委会将编写一份最后的研讨会报告，就推进TLS数据的获取、处理、分析和分发给科学界的各级提出建议。

1138279PhillipsThis grant supports a community workshop to define strategic directions for applications of Terrestrial Laser Scanning (TLS) for rapid high resolution surface mapping of natural and manmade features and how the geosciences community can best realize support for the technology. TLS is based on Light Detection and Ranging (LiDAR) technology and offers the capability to map surfaces with centimeter to sub-cm resolution with applications to the mapping of fault scarps, geologic outcrops, volcanic features, glacial features, barrier beach morphology; watershed drainage features; forest canopy and vegetative cover; and civil structures. The combination of repeat TLS surveys tied to GPS referenced locations allows for subtle change detection for the study of surface deformation in response to active tectonics, climate change and extreme events, and active volcanism. Long range TLS capabilities exist to map surfaces out to 1-2 km and thus offer advantages for rapid mapping of features that can pose human hazards using more traditional mapping techniques. High resolution TLS mapping complements spaceborne and terrestrial radar and LIDAR mapping modalities for studies requiring cm to sub-cm surface analysis A three day workshop is planned for late October, 2011 in Boulder, Colorado and will bring together approximately 50 geoscientists and students with experience and interests in exploiting TLS for the advancement of Earth system process understanding. The organizing committee will produce a final workshop report that will make recommendations for the advancement of TLS data acquisition, processing, analysis, and distribution to all levels of the scientific community.***
