This Geoinformatics award to the University of California San Diego supports a multi-year project that is collaborative with Arizona State University and UNAVCO, Inc. The project plan will improve upon and refine the capabilities of the OpenTopography Light Detection and Ranging (LiDAR) data services web portal that was initially jointly supported by NSF/EAR, NSF/OCI and NSF/CISE (EAR-0930731/EAR-0930643 and EAR-1226353). Efforts will entail development of strengthened interoperability, provision of a broadened suite of processing and data services, improved scalability via cloud and high performance computing, and provision of outreach and user support through short courses and workforce development. OpenTopography (OT) was designed to allow users web-based access Lidar generated high resolution topographic data sets and analysis tools in support of surface Earth process research, research training and education. A wide range of Earth Science fields including geomorphology, hydrology, glaciology, volcanology and neotectonics, have benefitted and will continue to benefit from OT data and tools. Continued development efforts for OT will expand capabilities to handle full waveform LiDAR, TLS data and bathymetric data as well as the continued ingestion of extant airborne LiDAR and terrestrial laser scanning (TLS) data sets from numerous sources including the National Center for Airborne Laser Swath Mapping Facility (NCALM), the UNVACO hosted TLS instrument pool, NOAA, US Bureau of Reclamation, USGS, Bureau of Land Management, the US Forest Service and numerous state airborne LiDAR data sets and Space Shuttle Radar Topography Mission (SRTM) global datasets. This work will expand topographic data collected with laser and photogrammetric technologies at a range of scales with a sustained emphasis on high-resolution topography (HRT; 1m/pix). At present OT?s rapidly growing data holdings currently include 186 LiDAR point cloud datasets (829 billion points) covering 180,122 km2. The OT user community has grown to over 8,100 registered users and more than 47,000 point cloud processing jobs have accessed over 1.6 trillion LiDAR returns. This support is congruent with NSFs mission of promoting the progress of science and may advance the national prosperity and welfare through improved public access to high resolution digital georeferenced topographic data sets with applications to geohazards assessment and mitigation including improved flood forecasting.***

加州大学圣地亚哥分校获得的地理信息学奖支持与亚利桑那州立大学和 UNAVCO, Inc. 合作的一个多年期项目。该项目计划将改进和完善开放地形光探测和测距 (LiDAR) 数据服务门户网站的功能，该门户网站最初由 NSF/EAR、NSF/OCI 和 NSF/CISE 联合支持 （EAR-0930731/EAR-0930643 和 EAR-1226353）。我们将努力加强互操作性，提供更广泛的处理和数据服务，通过云和高性能计算提高可扩展性，并通过短期课程和劳动力发展提供外展和用户支持。 OpenTopography (OT) 旨在允许用户基于网络访问激光雷达生成的高分辨率地形数据集和分析工具，以支持地球表面过程研究、研究培训和教育。 地貌学、水文学、冰川学、火山学和新构造学等广泛的地球科学领域已经并将继续受益于 OT 数据和工具。 OT 的持续开发工作将扩展处理全波形 LiDAR、TLS 数据和测深数据的能力，以及继续从众多来源获取现有机载 LiDAR 和地面激光扫描 (TLS) 数据集，包括国家机载激光测绘设施中心 (NCALM)、UNVACO 托管的 TLS 仪器池、NOAA、美国垦务局、 美国地质勘探局、土地管理局、美国林务局和众多国家机载 LiDAR 数据集和航天飞机雷达地形任务 (SRTM) 全球数据集。这项工作将扩展利用激光和摄影测量技术在一定范围内收集的地形数据，并持续强调高分辨率地形（HRT；1m/pix）。 目前，OT 的数据持有量快速增长，包括 186 个 LiDAR 点云数据集（8290 亿点），覆盖面积 180,122 平方公里。 OT 用户社区已发展到超过 8,100 个注册用户，超过 47,000 个点云处理作业已获取超过 1.6 万亿个 LiDAR 回报。 这种支持与 NSF 促进科学进步的使命相一致，并且可以通过改善公众对高分辨率数字地理参考地形数据集的访问以及在地质灾害评估和缓解（包括改进洪水预报）中的应用来促进国家繁荣和福利。***
