Collaborative Research: OpenTopography: A Cyberinfrastructure-Enabled Facility for High-Resolution Topographic Data and Tools

1226353 Baru该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）合作的一个为期三年的开发项目。该项目计划将改进和完善以前由NSF/EAR、NSF/OCI和NSF/CISE （EAR-0930731/EAR-0930643）联合支持的OpenTopography光探测和测距（LiDAR）数据服务门户网站的功能。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，以支持地表地球过程研究、研究培训和教育。该合同将开发OT2，这是一个可扩展的接口和平台，将允许科学家开发和插入功能模块，以及一个可扩展的系统，将允许存档增长和云计算模式提供的计算机服务。OT2将扩展处理全波形激光雷达、TLS数据和测深数据的能力。OT2将继续从众多来源获取现有的机载激光雷达和地面激光扫描（TLS）数据集，这些数据集是由国家机载激光测绘中心（NCALM）和UNVACO托管的TLS仪器池持续和扩展使用产生的机载激光雷达和TLS数据集。OT目前托管的数据还包括为EarthScope科学项目、关键区域天文台、NOAA、美国垦务局、美国地质勘探局、土地管理局、美国林务局和许多州机载激光雷达数据集飞行的机载激光雷达数据集。目前，OT拥有大约2000亿个激光雷达回波和数千个预先计算的数字高程模型（dem）和谷歌地球可读的kmz文件。OT管理部门记录了web门户的大量使用情况。该网站有超过1500名注册用户，每月的页面浏览量在5000到25000之间，超过12000次自动作业运行已经访问了超过2500亿次激光雷达回报。OT pi还报告说，已经下载了超过35000个预先计算的DEM图块，每月有超过70gb的谷歌地球图像流。用户群大约22%是学生，27%是学术研究人员，24%是政府科学家，15%是商业部门。＊＊＊

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. ***
