Abstract
Optical observation of the earth from a satellite has many useful applications, in fact, far too many to be satisfied by any particular embodiment of a scanning system. Each potential user -the cartographer, the urban development analyst, the agronomist, the water pollution sentry, the forester - has his own specific requirements for spectral bands, spatial resolution, sampling frequency, response time, and mapping fidelity. Therefore, instead of seeking a general purpose scanner, we must look for versatility at the design level. The particular approach described here, the roof wheel scanning technique*, leads to a rather large family of instruments applicable to satellite, airborne and other operations. (Ref. 1)
