"Landsat is the pioneering US (United States) land remote sensing satellite program which has provided a continuous supply of synoptic, repetitive, multispectral data of the Earth's land surfaces since 1972. Over the years a large international user community evolved along with the Landsat series. The program opened entire new fields of research, providing insights into geologic, agricultural, and land-use surveys, and led eventually to new paths of resource exploration - in all, for a better understanding of the Earth system."^^ .
