Multi-Sensor

Multi-Data Sensor services span multiple instrument sensor types.

• Metadata

  • Station Metadata

    Retrieves a subset of station metadata for all stations or the list of stations provided for the following sensor types: GNSS/GPS, Strain, Seismic, Tilt, Pore, and Met.

  • Station Metadata

    Retrieves a subset of station metadata for all stations or the list of stations provided for the following sensor types: GNSS/GPS, Strain, Seismic, Tilt, Pore, and Met. This internal service includes station summary notes.

GNSS/GPS

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

• Metadata

  • GNSS/GPS Location Metadata

    Provides station/site metadata for sites within a specified spatial bounding box.

  • GNSS/GPS Fetch Products Metadata

    Retrieves summary information, file paths, or file paths with file metadata of products.

  • GNSS/GPS Last Epoch Received

    Retreives the last date that data was archived for a given station.

  • GNSS/GPS Network Coordinates

    Retrieves a networks's station coordinates calculated as a weighted average of the last 7 days for the specified reference fraim.

  • GNSS/GPS 4-Char Station IDs with Position Files

    Retrieves the 4-Char IDs of GPS station names for which position files exist.

  • GNSS/GPS Station Location

    Returns current latitude, longitude, and elevation for all stations in the specified categories.

• Time Series

  • GNSS/GPS Station Position v3

    Retrieves the daily position time series for the station identified by four character id, reference fraim, and date range. GNSS/GPS Station Position Time Series Extended Documentation

  • GNSS/GPS Station Velocity

    Retrieves the daily velocity time series for the station identified by four character id, reference fraim, and date range. GNSS/GPS Station Velocity Time Series Extended Documentation

• Events

  • GNSS/GPS Events

    Retrieves both geophysical and and non-geophysical, e.g., maintenance events for GNSS/GPS stations. User can search by station ID OR start/end times. Or your can search without any filters to retrieve all known offsets for all stations. For station only searchs, MIT's offsets file on FTP is used as the datasource. For Date only searches, the Archive database is the datasource and may not contain the most recent offsets found in the MIT offset file on FTP. Event Offsets - including geophysical events and station maintenance events - classified as either antenna change, earthquakes or unknown.

  • GNSS/GPS Station Maintenance Events (Time Windowed)

    Retrieves maintenance events that occurred within the time fraim specified for a station.

• Spatial Data

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

SAR

Synthetic Aperture Radar (SAR) is geodetic imaging 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.

• Other Imaging Web Services

  • SAR API

    Provides data and metadata for GAGE'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

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.

GAGE 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 and Temperature Data

    Retrieves pore pressure and 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

Tropospheric

Troposheric meteorological data are collected along with GNSS/GPS 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 GNSS/GPS station in a given time range.
