This Division of Earth Sciences Instrumentation and Facilities Program (EAR/IF) award to the University of California San Diego supports a one-year collaborative project with Arizona State University (EAR-1833632) and UNAVCO, Inc (EAR-1833643). The award allows for continued maintenance and operation of a web-accessible cyberinfrastructure platform, OpenTopography (OT). OT provides web-based access to airborne light detection and ranging (lidar) topography data and data products and topographic data from portable terrestrial laser scanning (TLS), radar ranging, and photogrammetry at a range of scales in support of surface Earth process research, research training and education. The availability of high resolution digital topographic data and shallow water bathymetric data has been revolutionary for Earth and environmental sciences and engineering contributing to study of Earth surface processes (e.g., earthquake and volcanic processes associated crustal deformation, landslides, riverine sediment transport), vegetation dynamics and human modification of Earth's surface. Since OT's founding in 2009, over 62,000 unique users (registered users & guests) have run over 240,000 custom point cloud and raster jobs, processing nearly 4 trillion points. Most OT data sets are high resolution (1 m/pixel or 1 sample/sq. meter) but OT also provides access to global raster data (30-100 m/pixel). OT currently holds 256 LiDAR point cloud datasets covering ~217,000 km2. More than a trillion points are available for on-demand processing and download. The cost of data acquisition for topographic data hosted within OT data have an estimated value of $30 million. OT distributes data at various product levels at no cost to users and at least 290 peer-reviewed articles along with numerous theses and other publications have been produced using OT resources. OT draws on airborne LiDAR and terrestrial laser scanning (TLS) data sets from numerous sources including the EAR/IF supported National Center for Airborne Laser Swath Mapping Facility (NCALM) and the GAGE Facility hosted TLS instrument pool deployments that are funded through NSF and external research projects. Hosted data also includes 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 and Space Shuttle Radar Topography Mission (SRTM) global datasets. This support is congruent with NSF's 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.***This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

加州大学圣地亚哥分校地球科学仪器和设施计划 (EAR/IF) 部门授予的这一奖项支持与亚利桑那州立大学 (EAR-1833632) 和 UNAVCO, Inc (EAR-1833643) 的为期一年的合作项目。 该奖项允许持续维护和运营可通过网络访问的网络基础设施平台 OpenTopography (OT)。 OT 提供基于网络的机载光探测和测距（激光雷达）地形数据和数据产品以及来自便携式地面激光扫描（TLS）、雷达测距和摄影测量的地形数据，以支持地球表面过程研究，研究培训和教育。 高分辨率数字地形数据和浅水测深数据的可用性对于地球和环境科学和工程学来说是革命性的，有助于研究地球表面过程（例如，与地壳变形、滑坡、河流沉积物运输相关的地震和火山过程）、植被动态以及人类对地球表面的改造。 自 OT 于 2009 年成立以来，已有超过 62,000 个唯一用户（注册用户和访客）运行了超过 240,000 个自定义点云和栅格作业，处理了近 4 万亿个点。 大多数 OT 数据集都是高分辨率（1 m/像素或 1 个样本/平方米），但 OT 还提供对全局栅格数据（30-100 m/像素）的访问。 OT 目前拥有 256 个 LiDAR 点云数据集，覆盖范围约 217,000 平方公里。 超过一万亿个点可供按需处理和下载。 OT 数据中托管的地形数据的数据采集成本估计为 3000 万美元。 OT 免费向用户分发各种产品级别的数据，并且使用 OT 资源制作了至少 290 篇经过同行评审的文章以及大量论文和其他出版物。 OT 利用来自多个来源的机载 LiDAR 和地面激光扫描 (TLS) 数据集，包括 EAR/IF 支持的国家机载激光测绘设施中心 (NCALM) 以及由 NSF 和外部资助的 GAGE 设施托管的 TLS 仪器池部署研究项目。 托管数据还包括为 EarthScope 科学项目、关键区域天文台、NOAA、美国垦务局、USGS、土地管理局、美国林业局以及众多州机载 LiDAR 数据集和航天飞机雷达地形任务 ( SRTM）全球数据集。 这种支持与 NSF 促进科学进步的使命是一致的，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地质灾害评估和缓解（包括改进洪水预报）的应用来促进国家繁荣和福利。***该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
