Overview
LANDSAT-1 is the world first earth observation satellite launched by the United States in 1972 and a memorable satellite which has been recognized in availability being capable of observing the earth far from space. Its excellent observation ability brought about the importance of state-of-the-art remote sensing. Following LANDSAT-1, LANDSAT-2, 3, 4, 5 and 7 were launched, and currently LANDSAT-7 is operated as a main satellite.
LANDSAT-5 is equipped with Multispectral Scanner (MSS) and Thematic Mapper (TM). MSS is an optical sensor to observe the reflected solar radiation from the earth surface in four different spectral bands by bination of the optical system and the sensor. TM is a more advanced version of observation equipment than MSS, which observes the earth's surface in 7 spectral bands ranging from visible to thermal infrared regions.
LANDSAT-7 is equipped with Enhanced Thematic Mapper Plus (ETM+), the essor of TM. The observation bands are basically same seven bands as TM and the newly added band 8 with a 15m of high resolution.
