Resource inventory for multi-agency watershed planning

A demonstration study showed that NASA high-altitude color infrared (RB-57) imagery is useful for providing timely, relatively inexpensive, and accurate land-use information. The inventory encompassed 18 land-use categories for a 2590-square-kilometer Michigan watershed. The RB-57 photography was compared to alternative data collection methods (including ERTS and Skylab) and was found to have superior cost effectiveness for providing the desired information.
