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.
