Man and machine, a matching problem

Against a background of an I.T.C. proposal for an "Agricultural Real Time Imaging Satellite System", (ARTISS), some ideas about matching Man and Machine effort are given. Typical features of satellite MSS are reviewed. Many features other then pixel-wise Multi Spectral signatures should also be used in a classification process. Man is well equiped to use those extra features, but needs Machine help for efficient working. The aim of the ARTISS proposal is to provide developing countries with a dynamic survey system at reasonable cost. The author\´s ideas about the equipment for a minimum local groundstation are exposed. Implemention should use "intermediate technology", compatible with more advanced extensions in hard-and software.
