Algorithm Catalogue
The APEx Algorithm Catalogue is a valuable and innovative resource that provides access to a wide range of high-quality EO services. For users, it offers a central place to discover EO services that meet their specific needs. For EO projects, it serves as an easy and reliable platform to showcase and offer their services to a broader community, fostering collaboration and wider usage of their results.
Quality, validation, and benchmarks
The catalogue includes EO value-adding algorithms from different providers (Algorithm PIs), running on different EO platforms (Hosting Environments), and following one of two interoperability best practices: openEO or EO Application Packages.
Algorithms have undergone different levels of quality assurance and validation. Those originating from ESA R&D projects usually involve quality assurance and some stages of validation; these are marked as “validated” in the catalogue. Nevertheless, this does not mean an algorithm will always return a validated result. Applying these algorithms requires an understanding of their context and limitations. Algorithms labeled “community” were contributed by the wider EO community outside an ESA R&D project context. They have typically undergone less quality assurance and validation and should be used accordingly.
In addition, APEx runs technical benchmarks on some algorithms. These benchmarks check that an algorithm responds, functions, and returns results according to a predefined application scenario.
