One of the requirements for the Earth Observations Program is a multispectral imaging system for remote sensing in an earth orbiting satellite. This system should be capable of very broad spectral coverage so that a sufficient portion of the electromagnetic spectrum is available for examination to ensure that unique signatures of earth based details may be derived. Experimental evidence gathered during the past 5 years indicates that the region from 0.35 to 14 microns is particularly useful, with a spatial resolution of 25-100 feet desirable. Timeliness of data return and ease of subsequent data reduction are also important, particularly for such disciplines as Meteorology, Agriculture, pollution monitoring, etc.
