Welcome to the CoverageJSON wiki

While CoverageJSON is an open source format, the adoption by OGC of CoverageJSON as an OGC Community Standard requires voting membership in the OGC Technical Committee as either Technical, Principal or Strategic Member.

Otherwise, development of CoverageJSON is being conducted as an open process, through contributing to GitHub Issues and their resolution.

Meetings

Informal community meetings have started in 2025 to discuss and plan development of CoverageJSON. These are currently held using IBM Teams.
