The Impact of Earth Resources Exploration from Space
In contrast to the use of satellites for weather forecasting and for intercontinental communications, which have been available for more than fifteen years, surveys of earth resources with satellites have begun only a few years ago. The impact of earth resources surveys from space on society is therefore still much more a matter of speculation than a matter of record. Nevertheless, during three years of successful operation of the LANDSAT system, we have gained enough experience to assess the potential impact of global surveys with satellites of crops, forests, grasslands and soils on agricultural predictions: of snow cover and watershed morphology on water resources management; of land use, water and air quality on environmental protection: and of land forms and tectonic structure on mineral exploitation.
