APEx Algorithm Services Catalogue
Unlock the power of EO data and services with the APEx Algorithm Services Catalogue. This catalogue allows you to easily share, discover, and reuse results from multiple ESA-funded projects. Explore ready-to-use algorithm services that can be integrated into multiple project workflows, saving time and accelerating development.
Enabling the reuse and adaptation of EO algorithms
The Algorithm Service Catalogue serves as open and structured access points to ready-to-execute algorithm services developed in ESA-funded projects, hosted on different cloud platforms. By making results accessible, searchable, and ready for reuse, APEx supports researchers, developers, and platform providers in building upon existing work, reducing duplication of effort and fostering innovation.
An overview of reliable cloud-based services
The APEx Algorithm Services Catalogue offers streamlined access to EO algorithms developed and hosted as a service within existing cloud infrastructures. Each service entry includes rich metadata, comprehensive documentation, and direct links to execution environments on supported platforms. This offers multiple pathways for service execution.
Built according to APEx guidelines and leveraging standards such as the openEO API or OGC API Processes, the services are designed as modular components that can be integrated into more complex workflows. This approach also ensures compatibility with other tools in the APEx ecosystem, such as execution through the APEx JupyterLab and future integration with the upcoming APEx Upscaling Service, which will simplify the execution of algorithms over large geographical areas.
To ensure a high-quality catalogue, APEx applies continuous testing and benchmarking to many of the listed services. This enables APEx to maintain a reliable, up-to-date set of offerings with long-term performance and stability.
