What it is

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.

How it works

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

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

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

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

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.

Features

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.

Explore by region

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.

By the numbers

A growing global
catalogue.

A living archive of reproducible Earth Observation work and counting.
