This document provides an overview of the history and development of remote sensing from satellites. It discusses early satellite and manned spacecraft imaging from the 1960s with limited coverage. Meteorological satellites in the 1960s showed potential for remote sensing. Landsat, beginning in 1972, was the first satellite system designed for land remote sensing with global coverage and repeated visits. It included improvements over generations in spatial, spectral, and radiometric resolution. Other satellite systems discussed include SPOT, IKONOS, and instruments onboard the Terra satellite.
