  2. Landsat 7 - Wikipedia

    en.wikipedia.org/wiki/Landsat_7

    Landsat 7 Schematic. Landsat 7 was designed to last for five years, and has the capacity to collect and transmit up to 532 images per day. It is in a polar, Sun-synchronous orbit, meaning it scans across the entire Earth's surface. With an altitude of 705 km, it takes 232 orbits, or 16 days, to do so.

    Carrying the same Multi spectral Scanner (MSS) but also carrying an Enhanced Thematic Mapper, which added a 15m resolution panchromatic band. Landsat 7: 15 April 1999: Active: 25 years, 9 months and 27 days Operating with scan line corrector disabled since May 2003. [13] The main component on Landsat 7 was the Enhanced Thematic Mapper Plus (ETM+).

    Landsat Program: Landsat 5-8 Operational Land Imager (OLI) [5] Developed by Ball Aerospace & Technologies Corporation, the OLI is a crucial aspect of modern LandSat vehicles. Using 7000 sensors per band (Spectrum band), the OLI on NASA's most recent LandSat (LANDSAT 8) Satellite, will image/view the entire earth every 16 days.

    The first was placed aboard Landsat 4 (decommissioned in 2001), and another was operational aboard Landsat 5 up to 2012. [ 1 ] [2] TM sensors feature seven bands of image data (three in visible wavelengths, four in infrared ) most of which have 30 meter spatial resolution.

    Low-res color bands + High-res grayscale band = High-res color image. Such band combinations are commonly bundled in satellite data sets, for example Landsat 7, which includes six 30 m resolution multispectral bands, a 60 m thermal infrared band plus a 15 m resolution panchromatic band.

    Band 5 is helpful for ecology purposes and can help determine vegetation index or NDVI. Bands 6 and 7 are useful in geology and can help in distinguishing different saturated and unsaturated rocks and soils. Band 8 is helpful in creating images with very high resolution and precision. Band 9 is used for detecting different types of clouds. [7]
