NSF GAGE Facility

The NSF GAGE Facility 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, imaging data such as from SAR and TLS, strain and seismic borehole data, and meteorological data. Most of these can be accessed via web services. In addition, GPS/GNSS datasets, TLS datasets, and InSAR products are assigned digital object identifiers.

UNAVCO通过提供地理学家社群所使用的地球表面或附近各种传感器类型监测的岩石、冰雪和水的运动数据，以促进科研活动。经过处理，这些数据能够实现对离散点的毫米级表面运动检测与监测，并在数十至数百平方公里的区域内提供高分辨率应变图像。数据类型包括GPS/GNSS、SAR和TLS等成像数据，应变和地震钻孔数据，以及气象数据。大部分数据可通过网络服务访问。此外，GPS/GNSS数据集、TLS数据集以及干涉合成孔径雷达（InSAR）产品均被赋予数字对象标识符。
