1225810 ArrowsmithThis Geoinformatics award to Arizona State University (PI: Arrowsmith) supports a three year development project that is collaborative with the University of California, San Diego (PI: Baru). 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. ***

1225810 Arrowsmiththis Thisthis GeoInformatics授予亚利桑那州立大学（PI：Arrowsmith）支持了一个与加利福尼亚大学圣地亚哥分校（PI：Baru）合作的三年发展项目。 项目计划将改善并完善Opentography Light检测和范围（LIDAR）数据服务Web门户网站的功能，该网站先前由NSF/EAR，NSF/OCI和NSF/CISE（EAR-0930731/EAR-0930643）共同支持。 Opentography（OT）旨在允许用户基于Web的访问激光雷达生成高分辨率的地形数据集和分析工具，以支持地面过程研究，研究培训和教育。 该奖项将开发OT2，这是一个可扩展的界面和平台，它将允许科学家开发和插入功能模块，以及可扩展的系统，该系统将允许云计算方式提供的存档增长和计算机服务。 OT2将扩展功能以处理全波形激光雷德，TLS数据和测深数据。 OT2将继续摄入现有的空气降激龙和陆地激光扫描（TLS）数据集，这些数据集来自除空载激光雷达以外的许多来源和通过继续使用国家机载激光器式绘图设备（NCALM）和UNVACO托管托管TLS TLS TLS TLS托管池，从而产生的众多来源和TLS数据集。 现在，OT的托管数据还包括为地球科学项目，关键区观察者，NOAA，美国填海局，USGS，ISGS，土地管理局，美国森林服务局，美国森林服务局和许多州空降LIDAR数据集的托管LIDAR数据集。 目前，OT拥有约2000亿雷达的回报，数千个预计的数字高程模型（DEMS）和Google Earth可读的KMZ文件。 OT管理已记录了Web门户的大量使用。 超过1,500个注册用户，该网站每月可获得5,000至25,000页的视图，超过12,000个自动化的工作运行已访问超过2.500亿的激光雷达回报。 OT PIS还报告说，已经下载了35,000多个预先计算的DEM瓷砖，并且每月流式传输70 GB的Google Earth Imagery。 用户群约为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。 ***
