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.
Applications of Landsat Data are quite diverse, comprising Earth Science, Commercial
Applications, Mining Applications, Government and Military use. A few examples include
Mapping Land Cover change (Forest change, Urbanization, Etc), monitoring Agricultural
productivity, monitoring Wetland health, Mapping Geologic Resources, and targeting
habitats for vector-borne disease eradication. LANDSAT is a cornerstone of NASA's
Earth Observing System, providing moderate-resolution to high-resolution images.
