GEO Knowledge Hub
The open-source digital library for open, authoritative, and reproducible Earth Observation knowledge.
A living catalogue of
Earth Observation knowledge.
GEO Knowledge Hub is where Earth Observation applications find their audience. Packaged, cited, and forever reusable.
Open
Built on open standards. Resources flow freely between researchers, institutions, and communities. Discoverable to anyone, anywhere.
Authoritative
Curated by Earth Observation experts. Every package carries the trust of the GEO community and its programmes.
Reproducible
DOI-assigned, immutable, complete with provenance.
From scattered to sealed
in four steps.
A workflow built around the realities of Earth Observation work. Flexible enough for individuals, rigorous enough for institutions.
Create
Create
Step 01
Bring together datasets, code, environments, papers, stories. Every artefact your Earth Observation application depends on: local files, cloud buckets, repositories become first-class resources.
Describe
Describe
Step 02
Add metadata: title, authorship, license, vocabulary terms and more. The spine that lets others find and trust your work and the foundation of every citation.
Link
Link
Step 03
Associate resources around your Earth Observation application. Provenance becomes visible: lineage and dependency, the chain that turns a directory of files into a reproducible story.
Publish
Publish
Step 04
Seal it as a Knowledge Package. A permanent DOI joins the global catalogue. Citable, immutable, forever. The work becomes part of the EO record.
Built for reproducible
Earth Observation.
Every capability serves one goal: making EO work findable, citable, and trustworthy at the scale of a global community.
Communities
Curated thematic groups around shared challenges and missions.
Real-time exchange
Share knowledge with the GEO community as it happens.
Thematic search
Find applications by SDGs, Sendai Framework, or Paris Agreement.
Spatial search
Discover packages and resources by regions around the world.
Interoperability
Access materials through OAI-PMH and other established standards.
Rest API
Access and ingest data programmatically through a rich, documented API.
Preservation-friendly
Persistent identifiers and continuous integrity validation, by default.
GEO Principles
Created on the GEO Data Management and Sharing principles, by design.
A global community
of Earth Observation.
GEO Knowledge Hub connects researchers across continents. From data providers to end users, from local studies to global initiatives.
A growing global
catalogue.
A living archive of reproducible Earth Observation work and counting.
