Global digital elevation models (DEMs) have become routine operational inputs across mapping, environmental monitoring, modelling and Earth-observation workflows. Their broad coverage and global availability have made them data that many practitioners simply take for granted. But knowledge of the terrain and topography of Earth’s surface is fundamental for monitoring and understanding terrestrial ecosystems and the […]
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 validation of satellite-based land products relies heavily on in-situ or fiducial reference measurements (FRMs) collected over an ensemble of globally representative sites, providing consistent, high quality and traceable reference data. These sites must ensure adequate representation of different land cover and ecoclimatic conditions to enable unbiased satellite data validation at global scale. Evolving validation […]

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 […]
The CEOS Analytics Lab (CAL) is a cloud-based platform developed through a collaboration between the CEOS Systems Engineering Office (SEO), CSIRO, and the Universidad Adolfo Ibáñez’s Centre for Earth and Space. The platform’s goal is to address the growing challenges of processing increasingly large and complex Earth observation datasets by offering a collaborative, scalable environment […]
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 […]
After a few rounds of update and publication, it was found that the ECV Inventory format and update process could be improved to enhance its usage beyond the space agencies by making it an information base on CDRs for everybody. In 2024, the CEOS-CGMS WGClimate renamed the tool to the CDR Inventory and the EUMETSAT […]
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, […]
