For a decade or more research has been conducted which is intended to lead to the design of operational earth resource information systems. Clearly this research has not yet been completed. It does seem to be far enough along however, that an assessment relevant to future operational activities might well be possible and beneficial. In this paper a model operational system will be discussed not so much as a proposal for an actual system, but merely as a viable objective upon which to focus the research. Possible system configurations and constraints will be noted, and the trend in the cost for data processing will be discussed relative to such a system.
