Remote sensing with special reference to pollution

The recent development of satellites has made available enormous quantities of photographic and other forms of data about the surface of earth. These data have great potential for helping to solve human problem such as monitoring and controlling environmental pollution. All the wavelength regions for UV through microwave have practical applications. The synoptic regional coverage availability of data from inaccessible areas, and repeated coverage are advantages of satellite imagery. The great mass of industry and population creates pollution at a scale we are now not capable of handling. Even the monitoring of sources of pollution is beyond our present capabilities. The monitoring is the first step in pollution control and it can be accomplished by carefully designed remote sensing system. The feasibility of employing this technique in monitoring water pollution is indicated in this paper.
