Landsat 7 is a United States satellite launched in 1999 as part of the Landsat program, which has been providing Earth observation data since 1972. It is a valuable tool for a range of applications, including agriculture, forestry, and environmental monitoring. Landsat 7 is equipped with an advanced multispectral imaging instrument, providing data in the visible, near-infrared, and thermal infrared regions.

Landsat 7’s ETM+ sensor replicates the capabilities of the highly successful Thematic Mapper instruments on Landsat 4 and 5 but also includes new features that make it a more versatile and efficient instrument for global change studies, land cover monitoring/ assessment and large area mapping. The primary features are a panchromatic band with 15m spatial resolution; onboard, full aperture, 5% absolute radiometric calibration; and a thermal infrared channel with 60m spatial resolution.
