1226353 BaruThis Geoinformatics award to the University of California San Diego (PI: Baru) supports a three year development project that is collaborative with Arizona State University (PI: Arrowsmith). The project plan will improve upon and refine the capabilities of the OpenTopography Light Detection and Ranging (LiDAR) data services web portal that was previously jointly supported by NSF/EAR, NSF/OCI and NSF/CISE (EAR-0930731/EAR-0930643). 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. This award will develop OT2, an extensible interface and platform that will allow scientists to develop and plug in functional modules, and a scalable system that will allow archive growth and computer services provided by cloud computing modalities. OT2 will expand capabilities to handle full waveform LiDAR, TLS data and bathymetric data. OT2 will continue to ingest extant airborne LiDAR and terrestrial laser scanning (TLS) data sets from numerous sources beyond airborne LiDAR and TLS data sets produced by continued and expanding use of the National Center for Airborne Laser Swath Mapping Facility (NCALM) and the UNVACO hosted TLS instrument pool. Hosted data now at OT includes also airborne LiDAR data sets flown for EarthScope science projects, Critical Zone Observatories, NOAA, US Bureau of Reclamation, USGS, Bureau of Land Management, the US Forest Service and numerous state airborne LiDAR data sets. Currently, OT hosts some 200 billion LiDAR returns and thousands of pre-computed digital elevation models (DEMs) and Google Earth readable kmz files. OT management has documented high volume use of the web portal. There are over 1,500 registered users, the site gets between 5,000 and 25,000 page view per month and more than 12,000 automated job runs have accessed over 250 billion LiDAR returns. OT PIs also report that more than 35,000 pre-computed DEM tiles have been downloaded and over 70 Gb of Google Earth imagery is streamed per month. The user base is approximately 22% students, 27% academic researchers, 24% government scientists and 15% commercial sector. ***

1226353 Baru 这项地理信息学奖授予加州大学圣地亚哥分校（PI：Baru），支持与亚利桑那州立大学（PI：Arrowsmith）合作的为期三年的开发项目。 该项目计划将改进和完善 OpenTopography 光探测和测距 (LiDAR) 数据服务门户网站的功能，该门户网站此前由 NSF/EAR、NSF/OCI 和 NSF/CISE (EAR-0930731/EAR-0930643) 联合支持。 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。 该奖项将开发 OT2，一个可扩展的接口和平台，允许科学家开发和插入功能模块，以及一个可扩展的系统，允许档案增长和云计算模式提供的计算机服务。 OT2 将扩展处理全波形 LiDAR、TLS 数据和测深数据的能力。 OT2 将继续从机载 LiDAR 和 TLS 数据集之外的众多来源获取现有的机载 LiDAR 和地面激光扫描 (TLS) 数据集，这些数据集是通过继续和扩大使用国家机载激光测绘设施中心 (NCALM) 和 UNVACO 托管而产生的TLS 工具池。 OT 目前托管的数据还包括为 EarthScope 科学项目、关键区域观测站、NOAA、美国垦务局、美国地质调查局、土地管理局、美国林务局飞行的机载 LiDAR 数据集以及众多州机载 LiDAR 数据集。 目前，OT 托管约 2000 亿个 LiDAR 返回数据以及数千个预先计算的数字高程模型 (DEM) 和 Google 地球可读的 kmz 文件。 OT 管理记录了门户网站的大量使用。 该网站拥有超过 1,500 名注册用户，每月页面浏览量在 5,000 至 25,000 次之间，超过 12,000 次自动化作业运行已获取超过 2500 亿个 LiDAR 回报。 OT PI 还报告称，已下载超过 35,000 个预先计算的 DEM 图块，每月传输超过 70 GB 的 Google 地球图像。 用户群大约包括 22% 的学生、27% 的学术研究人员、24% 的政府科学家和 15% 的商业部门。 ***
