openEO web service
openEO represents an innovative community standard for geospatial data processing and analysis. This framework provides a novel approach to accessing, processing, and analyzing diverse Earth observation data. By adopting openEO, developers, researchers, and data scientists gain access to a unified and interoperable platform, empowering them to harness distributed computing environments and leverage cloud-based resources for addressing complex geospatial challenges.
The core concepts and functionalities of openEO instance in Terrascope are similar to the Copernicus Data Space Ecosystem. Therefore, to maintain up-to-date details and avoid duplication, it is advisable to refer to the openEO documentation available here. It is considered an entry point for users to get started with openEO.
However, the Terrascope endpoint is different from that of the Copernicus Data Space Ecosystem.
Terrascope offers an openEO endpoint at openeo.vito.be. Basic metadata is available at this link, and for a specific version, visit this link.
Logging In
Basic metadata about collections and processes is publicly available and does not require logging in. However, it is mandatory to authenticate for downloading EO data or running processing workflows.
The registration process when using openEO differs slightly from that of the Terrascope portal. Every user must register or log in using EduGAIN and social logins. This will start a one-time process that should enable login to all Terrascope services using your institution or social media credentials as mentioned here.
For more authentication information, refer to the openEO documentation.
After completing this, it will be possible to connect in Python using the following code:
import openeo
connection = openeo.connect("openeo.vito.be").authenticate_oidc()This process will display a website link and a code to enter. Once completed, connections can be set up in the same way for some time without repeating the authentication process.
Ensure that the Terrascope account is linked to EGI credentials which are also used by the European Open Science Cloud
Terrascope Layers
Products provided in Terrascope are available as ‘collections’ in openEO. Available collections are listed at this link. Detailed information can be obtained by appending the collection name, for example:
Additionally, a user can explore the layers in the viewer at viewer.terrascope.be.
