Landsat 9 →. 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 (USGS).
The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany.
Landsat 8/9 and Landsat Next spectral band comparison. Landsat 8 launched on 11 February 2013. It was launched on an Atlas V 401 from Vandenberg Air Force Base by the Launch Services Program. It will continue to obtain valuable data and imagery to be used in agriculture, education, business, science, and government.
Multispectral image of Bek crater and its ray system on the surface of Mercury, acquired by MESSENGER, combining images at wavelengths of 996, 748, 433 nm. The bright yellow patches in other parts of the image are hollows. Multispectral imaging captures image data within specific wavelength ranges across the electromagnetic spectrum.
Landsat 8 and Landsat-9 also acquires thermal data in two 10 and 11 bands from Thermal Infrared Sensor (TIRS). [ 18 ] Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) utilizes a unique combination of wide spectral coverage and high spatial resolution in the visible near-infrared through shortwave infrared to the thermal ...
English: On September 6, 2014, the Operational Land Imager (OLI) on Landsat 8 captured this view of the ongoing eruption of the Holuhraun lava field in Iceland. The false-color images combine shortwave infrared, near infrared, and green light (OLI bands 6-5-3). Ice and the plume of steam and sulfur dioxide appear cyan and bright blue, while ...
Spectral band in NIR region with similar 20 m ground resolution is band 8A (central wavelength 865 nm). Sentinel-2 NDWI for agricultural monitoring of drought and irrigation management can be constructed using either combinations: band 8A (864nm) and band 11 (1610nm) band 8A (864nm) and band 12 (2200nm) Both formulations are suitable.
The normalized difference vegetation index (NDVI) is a widely-used metric for quantifying the health and density of vegetation using sensor data. It is calculated from spectrometric data at two specific bands: red and near-infrared. The spectrometric data is usually sourced from remote sensors, such as satellites.
