The INTERFACE layer is a vital component of the INTERFACE project. The layer joins two previously developed technologies: Acube and Sen2Cube. Both engines provide the core functionalities for the tailored services meaning backend specific infrastructure and Analysis Ready Data processing and provisioning. Available within this layer are the following technologies: Dask & Dask gateway, a large spatiotemporal asset catalogue, an inference engine for querying semantic datacubes, a openEO processing engine, FORCE & SNAP for Analysis Ready Data creation, and many more!
