Mechanisms are provided for generating a composite service. A request to generate the composite service is received that identifies a geospatial region of interest for the composite service. One or more types of components needed to generate the composite service are determined and, for each component of a plurality of components of the one or more types of components, a corresponding spatial coverage characteristic is determined. A subset of components, from the plurality of components, is selected based on the spatial coverage characteristics of the plurality of components and the geospatial region of interest. The composite service is then generated based on the selected subset of components from the plurality of components.
