Since July 1972, various members of the U.S. Geological Survey (USGS) have been evaluating the utility of Landsat data. Through professional contacts with their counterparts in foreign countries, as well as in other United States agencies, this evaluation has been conducted on a worldwide multidisciplinary basis. The results of this effort have led to the definition of a proposed operational Landsat based on the following criteria: continuity with respect to Landsats-1, 2, and C; full availability of data on a global basis; and economic practicality. Unfortunately, the only Landsat-type satellites previously defined are for research purposes and are not designed to meet operational requirements. Neither the USGS nor any other government agency now has the charter to fund for and manage an operational Landsat. Therefore, this definition of the operational satellite is restricted to technical aspects with the hope that NASA will be authorized to build such a satellite and that the management problem for operations will be resolved before launch. In any case, an operational Landsat is considered justified and badly needed by all who would monitor the Earth's surface and would strive toward better utilization and conservation of the world's natural resources and environment.
