Web Services

UNAVCO is working to provide unified access to our Web Services based on consistent interfaces, API documentation, and best practices. Currently, only a portion of UNAVCO Web Services are presented in this unified format and are listed here by instrument/sensor type, e.g., GPS/GNSS or Geodetic Imaging, and data type, e.g., Metadata or Time Series Data. We list Production, Beta, and Deprecated services here. The suite of unified web services will become more comprehensive over time. Our various non-unified web services are also listed here for completeness.

See our Versioning page for descriptions of web service versioning methods and types of releases.

See our Release Notes for a list of changes in the current release and past releases.

Index

Multi-Sensor

Multi-Data Sensor services span multiple instrument sensor types.

  • Metadata

    • Station Metadata
      Retrieves location metadata for the following sensor types: GPS/GNSS, Strain, Seismic, Tilt, Pore, and Met. User can use circular or bounding box spatial constraints. Also allows user to retrieve all stations by project or station type.

GPS/GNSS

GPS/GNSS data refer to raw measurements collected from GPS/GNSS receivers and antennas at survey points; processed results such as geodetic positions of survey points; or geologic velocities of those points.

Imaging

Geodetic Imaging data is data collected by techniques that use electromagnetic waves for tracking centimeter-scale motions at the Earth’s surface over several square meters to hundreds of square kilometers. Such methods include LIDAR and SAR (synthetic aperture radar).

  • Other Non-Unified Imaging Web Services

    • SAR API
      Provides data and metadata for UNAVCO's SAR data holdings via a variety of query parameters. NOTE: These services are being maintained although they do not conform to our unified web services design.
  • Metadata

    Metadata web services will be listed here that provide results in a variety of formats, e.g., CSV, JSON, XML, etc.

  • Time Series

    Time series data web services will be listed here that provide results in a variety of formats, e.g., CSV

  • Events

    Event data web services will be listed here that provide results in a variety of formats, e.g., CSV.

  • Spatial Data

    Spatial data web services will be listed here that provide results in a variety of formats, e.g., KML.

Borehole Sensors

Geodetic strain data is collected by four-component deep borehole tensor strainmeters that record transient deformation signals yielding information about the physical properties of the surrounding rock. Pore pressure and temperature readings are collected by pore pressure sensors co-located with borehole strainmeters. Tilt data is collected by shallow borehole tiltmeters co-located with borehole strainmeters and seismic stations.

UNAVCO maintains more than 70 borehole seismometers as part of the PBO Borehole Seismic Network with sites. The sensors are Sonde-2 seismometers. The data set generated by the PBO Borehole Seismic Network has become an integral component to research being done in regional seismic networks, such as those in Anza, California, and Yellowstone National Park.

  • Time Series

    • Strain Level 2 Time Series Data
      Provides strain level 2 data for a given station and time range. Data returned includes uncorrected and corrected strain for each channel, and uncorrected and corrected values for areal, differential extension, and shear strain.
    • Pore Pressure Data
      Retrieves pore pressure data for the station identified by four character id, and start and end times.
    • Pore Temperature Data
      Retrieves pore temperature data for the station identified by four character id, and start and end times.
    • Tilt Data
      Retrieves tilt data for the station identified by four character id, and start and end times.
    • Seismic Station Counts Time Series Data
      Returns: date, count.
  • Event Data

    • Seismic Station Earthquake Events
      Retrieves information for earthquakes whose epicenters are within the given radius from the specified station, have a magnitude greater than the specified minimum and occurred within the given time frame.

Troposheric

Troposheric meteorological data are collected along with GPS/GNSS and other forms of geophysical data to enhance the datasets, contribute to network monitoring information, and provide additional information for interpretation of deformation signals.

  • Time Series

    • Meteorological Time Series Data
      Provides meteorological time series data collected by instruments at the specified GPS/GNSS station in a given time range.
  • Metadata

    Metadata web services will be listed here that provide results in a variety of formats, e.g., CSV, JSON, XML, etc.

  • Event Data

    Event data web services will be listed here that provide results in a variety of formats, e.g., CSV.

  • Spatial Data

    Spatial data web services will be listed here that provide results in a variety of formats, e.g., KML.

Miscellaneous

In addition to geodetic sensor data, UNAVCO provides web services for a variety of miscellaneous UNAVCO assets.

Deprecated Web Services

The following web services are deprecated and remain available only to provide time for users to update their code. Please see their new equivalent (if available) in the Production area.
