5. What is openEO?

6. What is
openEO?
openEO is an open-source API developed to
simplify access, process and analyse of
Earth Observation (EO) data. Users can
seamlessly share code, workflows and data
processing methods across platforms and
tools, fostering easy accessibility,
scalability, and reproducibility.



Added Value with openEO

•Unified and straightforward access to
multiple Earth observation datasets

•Scalable processing

•Independent

•Interoperable and Reproducibility work
flow

•FAIR and open-science principles

7. openEO concept
• multidimensional arrays with one or more spatial or temporal
dimension
• Any representation of the data cube is fine
(meaning – dimensions can be switched in the display)
• Users do not deal with files, formats, data loading or memory
management
