APEx Algorithm Service Catalogue

The APEx Algorithm Services Catalogue is a valuable and innovative resource that grants access to a wide array of high-quality EO services. It serves as a central hub for users to discover EO services tailored to their specific requirements. For EO projects, this catalogue provides an intuitive and reliable platform to showcase and offer their services to a broader community, thereby fostering collaboration and enhancing the utilization of their results.

All algorithms registered in this repository are seamlessly integrated and visualized within the APEx Algorithm Services Catalogue. This integration relies on properties defined in the OGC API Records stored in a JSON format. The information gleaned from the OGC API Records is instrumental in constructing both the overview of the catalogue and the detailed pages of each service.

Title Title of the page properties.title
Description The full description of the service If there is an entry in the properties.links section with rel equal to application, it will use this URL to fetch the description from the openEO UDP or CWL file. If the resource is protected or if it was not possible to fetch the information, this part will contain the value of properties.description.
Preview Images shown as preview of the service An image will be shown for each entry in the properties.links section where rel is set to preview.
Execution Information Details for the execution of the service This information is based on the properties.links where rel is equal to service or application. If the openEO UDP or CWL is publicly available, additional information will be fetched from its definition and automatically visualised in this section.
