GCRI · Space and Earth Observation
STEM foundation of Space and Earth Observation
The science, technology, engineering and mathematics Space and Earth Observation rests on. Each method has a canonical page in the STEM Commons, hosted by the Global Centre for Risk and Innovation (GCRI), and a page here on how it is applied in this field.

Why Earth observation needs this combination of methods.
EO work combines Earth observation and geospatial methods with spatial statistics for accuracy, space systems and communications for the infrastructure, computing for processing and physics for sensors. Accuracy assessment ties them together: no EO product is used in a decision until its error against ground data is known for the place concerned.
EO work combines Earth observation, geospatial and spatial statistics with space systems, computing, communications and physics.
Grounding makes claims checkable.
When a finding names the methods it depends on, a reader can see its assumptions and limits, and an expert in that method can challenge it.

Contribute evidence from this page.
Reports is the Consortium’s quarterly publication. What you know about this subject can become evidence, a case or a correction in the next edition, credited to you and published under CC BY 4.0 where it is your own work.
- EmailGateway GW-GCRISend it from this pageEvidence, a correction, a case, a method, a review, a translation or profile input. It arrives tagged with this page, so the editor who owns it receives it.
- ZenodoOpen depositDeposit it and submit to the communityPublish your own record on Zenodo with your ORCID iD, then submit it to the Reports community there. Curators review it; the DOI stays yours.

Never send personal data, sensitive infrastructure detail or anything you have no right to share. A contribution is reviewed before use; sending it confers no authorship or editorial rights, and sponsorship never buys a finding.

Information and enquiries are open today. An enquiry receives a reference and names the next step; applications, payments, compute allocations and registrations open only when their team, terms and review capacity exist.
