Time Series Data in Geostreams

PreviousData Processing PipelineNextData Backup

Last updated 5 years ago

Several extractors push data to the Clowder Geostreams database, which allows registration of data streams that accumulate datapoints over time. These streams can then be queried, visualized and downloaded to get time series of various measurements across plots and sensors. Learn more about data in this database in this tutorial

The TERRA-REF Geostreams database organizes data into three levels:

  • Location (e.g. plot, or a stationary sensor)

    • Information stream (a particular instrument's data, or a subset of one instrument's data)

      • Datapoint (a single observation from the information stream at a particular point in time)

Sensor destinations

Here, the various streams that are used in the pipeline and their contents are listed.
