Interoperability of Earth observation (EO) data and services depends not only on shared technical standards but also on a common understanding of language and meaning. Ensuring that data, messages and services are not only transmitted but also correctly understood across different stakeholders is fundamental to achieving interoperability in EO. Without a shared understanding of terms, […]

Post-launch calibration and validation (Cal/Val) is essential to ensure that satellite observations remain accurate, comparable and fit for purpose throughout their operational lifetime. The concept of a Fiducial Reference Measurement (FRM) was established by the EO community as a practical means to identify independent reference data that demonstrably meets quality assurance principles. The CEOS-FRM initiative, […]

Interoperability refers to the ability of data, systems, and services that are often developed independently to work together seamlessly. For Earth observation (EO) data providers and distributors, this means enabling users to discover, access, integrate, and analyse data from multiple sources without unnecessary technical, semantic, or policy barriers. Interoperability of data and services in the […]
