UNAVCO’s Geodetic Data Services

UNAVCO 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, GPS/GNSS data sets, TLS data sets, and InSAR products are assigned digital object identifiers. See our About Data page for more information. See our data help page to request support or custom data acquistion.

Data Management All UNAVCO-facilitated data and metadata must be archived by UNAVCO upon collection. Data providers are responsible for providing attribution information with submitted data, including sponsor and provider contact information. The Geodetic Data Services (GDS) program manages a complex set of metadata and data flow operations providing a wide range of geodetic/geophysical observations to scientific and educational communities. Sensors currently include GPS (downloaded files and streaming real- time (RT-GPS)), borehole geophysics instrumentation (strainmeters, tiltmeters, seismometers, pore pressure and meteorological sensors), long baseline laser strainmeters, and terrestrial laser scanners. Field data are acquired either from continuously operating sites or episodic “campaign” surveys conducted the community. UNAVCO also acquires and distributes satellite synthetic aperture radar (SAR) data from foreign space agencies. GDS services include data operations (managing metadata; data downloading, ingesting and preprocessing); data products and services (generating processed results and QA/QC and state-of- health monitoring); data management and archiving (distribution and curation); cyberinfrastructure (CI); and information technology (systems and web administration). In order to perform this mission, GDS maintains a technical staff, onsite and offsite computer facilities with networking, servers and disc storage, and manages a number of subawards to university groups who provide additional products, software and training. +A85:G85
Data Policy The current UNAVCO Data Policy makes the default accessibility for all data immediately openly-accessible, with no exclusive-use period. However, there is a clause in the policy that allows for an exclusive-use period with approval of the sponsor. This sponsor-approved exclusive-use period can potentially apply to any class of data, i.e. campaign, permanent, continuous, semi-continuous, with comms, without comms, etc. Archiving of data All UNAVCO-facilitated data and metadata must be archived by UNAVCO upon collection. Data providers are responsible for providing attribution information with submitted data, including sponsor and provider contact information. Accessibility Metadata will be made publicly available when placed in the archive. Data will be made publicly available when placed in the archive, unless an investigator has documented a period of exclusive use that is specified by the sponsor, typically in the award letter. Attribution By accessing data from the UNAVCO archive, users agree to appropriate attribution to providers and their sponsors, acknowledgment of UNAVCO and its sponsors, and to adherence to professional and ethical standards. Disclaimer UNAVCO makes no guarantee of the quality, reliability, usability, availability, or suitability of any UNAVCO data for any particular purpose. UNAVCO data should not be used for any life-critical functions. Users assume all risks and liabilities, direct or indirect, associated with any use of UNAVCO data. NOTE: High-rate GPS data and Realtime Streaming GPS data are subject to separate policies.
Data Sharing Principle The current UNAVCO Data Policy makes the default accessibility for all data immediately openly-accessible, with no exclusive-use period. However, there is a clause in the policy that allows for an exclusive-use period with approval of the sponsor.
