First launched in 1972, the Landsat Satellite Series constitutes one of the longest
continuous records in Earth Observation. The objective of the Landsat Program has
always been to provide Multispectral Imagery of the Earth's Land Areas at Moderate
to High Resolution, (28.50 - 90.00 Meter Horizontal Resolution) to support Resource
Assessment, Land Cover Mapping, and to track Inter Annual changes in the Environment.
