NSF Geodetic Facility for the Advancement of Geoscience

The NSF GAGE Facility (hereafter referred to as GAGE) operated by EarthScope Consortium promotes research by providing access to data that our community of geodetic scientists uses for quantifying the motions of rock, ice and water that are monitored by a variety of sensor types at or near the Earth's surface. After processing, these data enable millimeter-scale surface motion detection and monitoring at discrete points, and high-resolution strain imagery over areas of tens of square meters to hundreds of square kilometers. The data types include GPS/GNSS, SAR and Lidar/SfM, strain and seismic borehole data, and Tropospheric data. Most of these can be accessed via web services. In addition, GNSS/GPS data sets, TLS data sets, and InSAR products are assigned digital object identifiers. This resource was formerly (and may still in some cases, still be) called UNAVCO.由EarthScope联盟运营的美国国家科学基金会（National Science Foundation, NSF）GAGE设施（下文简称GAGE），通过向大地测量科学家群体开放数据获取渠道以推动相关研究。该设施采集的数据可用于量化岩石、冰体与水体的运动——这类运动通过多种传感器在地球表面或近地表区域完成监测。经处理后，这些数据可实现离散点位的毫米级地表运动检测与监测，以及覆盖数十平方米至数百平方公里范围的高分辨率应变成像。数据类型涵盖全球定位系统/全球导航卫星系统（GPS/GNSS）、合成孔径雷达（SAR）、激光雷达（Lidar）与运动恢复结构（SfM）、钻孔应变与地震数据，以及对流层数据。其中绝大多数数据可通过Web服务获取。此外，GNSS/GPS数据集、地面激光扫描（TLS）数据集与干涉合成孔径雷达（InSAR）产品均已分配数字对象标识符（DOI）。该资源此前（部分场景下目前仍）被称为UNAVCO。
