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

1138279 Phillips该补助金支持社区研讨会，以确定陆地激光扫描（TLS）应用于自然和人造特征快速高分辨率表面测绘的战略方向，以及地球科学界如何最好地实现对该技术的支持。 TLS以光探测和测距（LiDAR）技术为基础，能够以厘米至亚厘米分辨率绘制表面，并应用于断层崖、地质露头、火山地貌、冰川地貌、屏障海滩形态、流域排水地貌、森林树冠和植被以及土木结构的绘制。 与GPS参考位置相关的重复TLS调查的组合允许细微的变化检测，以研究对活动构造、气候变化和极端事件以及活火山活动的响应。 存在远距离TLS功能，可以绘制1-2公里的表面，从而为使用更传统的测绘技术快速绘制可能对人类造成危害的特征提供优势。 高分辨率TLS测绘补充了星载和地面雷达以及LIDAR测绘模式，用于需要厘米至亚厘米表面分析的研究 计划于2011年10月下旬在科罗拉多的博尔德举办一个为期三天的研讨会，届时将有大约50名地球科学家和学生聚集在一起，他们在利用TLS促进地球系统过程理解方面有经验和兴趣。 组委会将编写一份最终研讨会报告，为推进TLS数据采集、处理、分析和向各级科学界分发提出建议。

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.***
