Land cover determination is a common use of Landsat imagery around the world. [23] Landsat imagery provides one of the longest uninterrupted time series available from any single remote sensing program, spanning from 1972 to present. [24]
Landsat 8 is an American Earth observation satellite launched on 11 February 2013. It is the eighth satellite in the Landsat program; the seventh to reach orbit successfully. . Originally called the Landsat Data Continuity Mission (LDCM), it is a collaboration between NASA and the United States Geological Survey (USG
The satellite weighs 1973 kg, is 4.04 m long, and 2.74 m in diameter. Unlike its predecessors, Landsat 7 has a solid-state memory of 378 Gbits (roughly 100 images). The main instrument on board Landsat 7 is the Enhanced Thematic Mapper Plus (ETM+), a whisk broom scanner image sensor.
NASA's Landsat satellites have consistently made history in Earth observation since the project's first launch in 1972, with this year marking 50 years of innovation and science. Its influence may ...

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. Enhanced Thematic Mapper + (ETM+) [6] [7] Used in conjunction with OLI, the ETM + images the Earth in 30m Pixels. To ensure quality, each scan has a correction due to Scan-Line correcting.
Landsat-7: Active NASA and USGS 1999 Images Earth's land surfaces and coastal areas with global coverage at high spatial resolution. [19] Landsat-8: Active NASA and USGS 2013 Follow on to Landsat-7 with improved imager OLI and thermal sensor TIRS. Landsat-9: Active NASA and USGS 2021 Follow on to Landsat-8 with OLI sensor and thermal sensor TIRS-2.
The Operational Land Imager (OLI) is a remote sensing instrument aboard Landsat 8, built by Ball Aerospace & Technologies. Landsat 8 is the successor to Landsat 7 and was launched on February 11, 2013. [1] OLI is a push broom scanner that uses a four-mirror telescope with fixed mirrors.
