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.

这项地球科学仪器仪器设施计划（EAR/IF）授予加利福尼亚大学圣地亚哥分校颁发了与亚利桑那州立大学（EAR-1833632）和UNAVCO（EAR-1833643）的一年合作项目。 该奖项允许继续维护和操作网络访问的网络基础设施平台Opentography（OT）。 OT提供了基于Web的访问空气传播的光检测和范围（LIDAR）的地形数据和数据产品以及从便携式陆地激光扫描（TLS），雷达范围和摄影指控的地形数据，以支持表面接地过程，研究，研究训练和教育。 高分辨率数字地形数据和浅水水域学数据的可用性对于地球和环境科学和工程学的革命性是革命性的，这有助于研究地面表面过程（例如，地震和火山过程相关的地壳变形，地下滑坡，地面，地块，河流沉积物，河流沉积物运输），植被动力学和人类地面表面的动态。 自2009年OT成立以来，超过62,000个唯一用户（注册用户和来宾）已运行240,000多个自定义点云和栅格工作，处理了近4万亿分。 大多数OT数据集是高分辨率（1 m/pixel或1个样本/平方米），但OT还提供了对全球栅格数据（30-100 m/pixel）的访问。 OT目前持有256个LIDAR点云数据集，覆盖约217,000 km2。 可用于按需处理和下载的超过万亿点。 OT数据中托管的地形数据的数据获取成本的估计值为3000万美元。 OT无需向用户分发各种产品级别的数据，并使用OT资源生产了至少290份经过同行评审的文章以及许多论文和其他出版物。 OT借鉴了来自众多源的机载激光雷达和陆地激光扫描（TLS）数据集，包括耳朵/如果支持的国家空降激光施加映射设施（NCALM）和量具设施的TLS TLS仪器池部署，这些仪器由NSF和外部研究项目提供资金。 托管的数据还包括为地球科学项目，关键区观测站，NOAA，美国填海局，USGS，USGS，土地管理局，美国森林服务局以及许多州空降林业数据集和众多州航天飞机航天飞机雷达雷达仪（SRTM）全球数据集的众多国家机载数据集（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，并可能通过改善公众访问高分辨率数字地理区域的高分辨率地形数据集，并在地理扎华评估和缓解措施中申请，包括改进的洪水预测，包括改进的洪水预测。
