The CEOS Visualization Environment (COVE) tool is a browser-based system that leverages Google-Earth to display satellite sensor coverage areas and identify coincidence scene locations. The NASA CEOS System Engineering Office (SEO) worked with the Committee on Earth Observing Satellites (CEOS) Working Group on Calibration and Validation to develop the COVE tool.

CEOS is currently operating and planning hundreds of Earth observation satellites. Standard Calibration and Validation (Cal/Val) exercises to compare near-simultaneous surface observations and identify corresponding image pairs are time-consuming and labor-intensive. The COVE suite of tools has been developed to make such tasks easier.  The suite currently consists of the following tools:

  • The COVE Tool enables users to visualize satellite instrument coverage tracks and calculate coincidences.  The COVE Tool features real-time collaboration and support for multiple viewports.  Some COVE data can be exported to STK scenarios.
  • The Rapid Acquisition Tool enables users to quickly identify potential acquisitions over specified regions.  This acquisition data can be downloaded in .csv spreadsheet format.
  • The Mission and Instrument Browser allows users to view COVE's database of missions and instruments.  The modeling assumptions for each mission/instrument are included.

Additionally, some COVE functionally is available through an HTTP-based API.
