  2. False color - Wikipedia

    en.wikipedia.org/wiki/False_color

    A traditional false-color satellite image of Las Vegas. Grass-covered land (e.g. a golf course) appears in red. In contrast to a true-color image, a false-color image sacrifices natural color rendition in order to ease the detection of features that are not readily discernible otherwise – for example the use of near infrared for the detection of vegetation in satellite images.

  3. Landsat program - Wikipedia

    en.wikipedia.org/wiki/Landsat_program

    A false-color image of irrigated fields near Garden City, Kansas, taken by the Landsat 7 satellite. In 2015, the Landsat Advisory Group of the National Geospatial Advisory Committee reported that the top 16 applications of Landsat imagery produced savings of approximately 350 million to over 436 million dollars each year for federal and state ...

  4. SeaWiFS - Wikipedia

    en.wikipedia.org/wiki/SeaWiFS

    A false color SeaWiFS image shows a high concentration of phytoplankton chlorophyll in the Brazil Current Confluence region east of Argentina. Warm colors indicate high chlorophyll levels, and cooler colors indicate lower chlorophyll. SeaWiFS data are freely accessible from a variety of websites, most of which are government run.

  5. Coastal zone color scanner - Wikipedia

    en.wikipedia.org/wiki/Coastal_zone_color_scanner

    Ocean color around Tasmania (false color). Red and orange colors indicate high levels of phytoplankton. The coastal zone color scanner (CZCS) was a multi-channel scanning radiometer aboard the Nimbus 7 satellite, predominately designed for water remote sensing. Nimbus 7 was launched 24 October 1978, and CZCS became operational on 2 November 1978.

  6. Synthetic-aperture radar - Wikipedia

    en.wikipedia.org/wiki/Synthetic-aperture_radar

    The surface of Venus, as imaged by the Magellan probe using SAR, colorized with false color. SAR is capable of high-resolution remote sensing, independent of flight altitude, and independent of weather, as SAR can select frequencies to avoid weather-caused signal attenuation. SAR has day and night imaging capability as illumination is provided ...

  7. VNIR - Wikipedia

    en.wikipedia.org/wiki/VNIR

    A VNIR image of the Ghadamis River in Libya.This is a false-color composite image made using near-infrared, green, and blue wavelengths. The visible and near-infrared (VNIR) portion of the electromagnetic spectrum has wavelengths between approximately 400 and 1100 nanometers (nm). [1]

  9. Multispectral pattern recognition - Wikipedia

    en.wikipedia.org/wiki/Multispectral_pattern...

    Remote sensing systems gather data via instruments typically carried on satellites in orbit around the Earth. The remote sensing scanner detects the energy that radiates from the object or area of interest. This energy is recorded as an analog electrical signal and converted into a digital value though an A-to-D conversion.
