This document discusses on-demand EO processing services using the Web Processing Service (WPS) standard in a federation of European ground segments. It describes how WPS can be used to publish, describe, and execute geospatial processes. It also provides examples of using WPS for image processing, such as assisted land cover classification, and discusses the benefits of a federated approach over centralization.
