As the number and variety of Earth observation (EO) platforms and data providers continue to expand, seamless data and service integration across these organisations is an important requirement. The CEOS Interoperability Handbook sets out a clear framework for addressing this challenge, focusing on five key factors: Vocabulary, Architecture, Quality, Interface, and Policy. Together, these factors […]

The CEOS Interoperability Handbook provides a shared framework for achieving interoperability across global Earth observation (EO) systems. It describes five core factors of interoperability: Vocabulary, Architecture, Quality, Interface and Policy, which together enable the discovery, access, visualisation, and processing of data from multiple sources. Within this framework, the Interface factor serves as the practical execution […]

The CEOS Interoperability Handbook identifies five core factors required to enable effective interoperability of Earth observation (EO) systems and datasets: Vocabulary, Architecture, Quality, Interface, and Policy. The framework recognises that interoperability is not only about exchanging data, but also about maintaining confidence in the quality and meaning of that data when it is shared between […]

Interoperability in Earth observation (EO) must be addressed in a structured and comprehensive manner, bringing together multiple factors, including Vocabulary, Architecture, Interface, Quality and Policy. The CEOS Interoperability Framework provides a common approach for ensuring that EO data and services can be discovered, accessed, combined, and used effectively across different systems and organisations.  Within the […]

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 […]
