Help with Data

Request Support

Request Support for any of the specific data topics listed below. A project manager will be assigned for complex requests that require multiple services, coordination, and management.

• GPS/GNSS Data Processing Service is available for high-precision GPS/GNSS products, utilizing the existing GAGE processing infrastructure
• Data Archiving is available for community GPS/GNSS data and data products (GPS time series and velocities), high-rate (1-Hz and higher rates) GPS data (upon request), SAR data, TLS data, and related metadata to archive for long-term secure storage and easy retrieval. The Archive primarily stores high-precision geodetic data used for research purposes, collected under projects sponsored by NSF and NASA. Please see Submission of Data for more detailed information for submitting GPS/GNSS or TLS data to GAGE for archiving.

A Custom Data Request can be made for certain special situtations at certain sites (please see the form for other requirements):

• GPS/GNSS high rate (i.e. 1- or 5-Hz rate) (note: for real-time GPS/GNSS, use email address below)
• borehole strain (i.e. processed 1-Hz rate)
• borehole seismic (i.e. 200-Hz rate)
• surface laser strain (i.e. processed 1-Hz rate)
