Of its 11 bands, only those in the very shortest wavelengths (bands 1–4 and 8) sense visible light – all the others are in parts of the spectrum that we can’t see. Band 7 Near-Infrared (0.8 to 1.1 µm) Six detectors for each spectral band provided six scan lines on each active scan; Ground Sampling Interval (pixel size): 57 x 79 m; Scene size: 170 km x 185 km (106 mi x 115 mi) Visit Landsat 1-5 MSS for more information. Landsat 1 was launched on July 23, 1972; at that time the satellite was known as the Earth Resources Technology Satellite (ERTS).It was the first Earth-observing satellite to be launched with the express intent to study and monitor our planet’s landmasses. To understand the value of all the bands, let’s look at them each in turn: The Bands The true-color view from Landsat is less than half of what it sees.

Landsat is the pioneering US (United States) land remote sensing satellite program which has provided a continuous supply of synoptic, repetitive, multispectral data of the Earth's land surfaces since 1972. Spacecraft Launch Mission Status Sensor Complement References. Landsat 4 & Landsat 5: with the MSS and Thematic Mapper (TM) instruments on the Multi-mission Modular Spacecraft (MMS) platform. Landsats 1, 2, and 3 were modified Nimbus meteorlogical satellites. Spacecraft Facts. Landsat 7 Enhanced Thematic Mapper Plus (ETM+) images consist of eight spectral bands with a spatial resolution of 30 meters for Bands 1 to 7.

The resolution for Band 8 (panchromatic) is 15 meters. Landsat 1 MSS Collection 1 Tier 1 DN values, representing scaled, calibrated at-sensor … All bands can collect one of two gain settings (high or low) for increased radiometric sensitivity and dynamic range, while Band 6 collects both high and low gain for all scenes. Landsat-1 to Landsat-3.
