  2. Remote sensing - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing

    An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others.

  4. Satellite imagery - Wikipedia

    en.wikipedia.org/wiki/Satellite_imagery

    There are five types of resolution when discussing satellite imagery in remote sensing: spatial, spectral, temporal, radiometric and geometric. Campbell (2002) [ 6 ] defines these as follows: Spatial resolution is defined as the pixel size of an image representing the size of the surface area (i.e. m 2 ) being measured on the ground, determined ...

  5. Earth observation - Wikipedia

    en.wikipedia.org/wiki/Earth_observation

    Earth observation (EO) is the gathering of information about the physical, chemical, and biological systems of the planet Earth. [1] It can be performed via remote-sensing technologies (Earth observation satellites) or through direct-contact sensors in ground-based or airborne platforms (such as weather stations and weather balloons, for example).

  6. Landsat program - Wikipedia

    en.wikipedia.org/wiki/Landsat_program

    Finally, by 1970 NASA had a green light to build a satellite. Remarkably, within only two years, Landsat 1 was launched, heralding a new age of remote sensing of land from space. [3] The Hughes Aircraft Company from Santa Barbara Research Center initiated, designed, and fabricated the first three Multispectral Scanners (MSS) in 1969.

  7. Aerial survey - Wikipedia

    en.wikipedia.org/wiki/Aerial_survey

    Typical data collected includes aerial photography, Lidar, remote sensing (using various visible and invisible bands of the electromagnetic spectrum, such as infrared, gamma, or ultraviolet) and geophysical data (such as aeromagnetic surveys and gravity measurements). It can also refer to a chart or map made by analyzing a region from the air.

  8. Satellite - Wikipedia

    en.wikipedia.org/wiki/Satellite

    A satellite or artificial satellite [a] is an object, ... Earth observation satellites are designed to monitor and survey the Earth, called remote sensing.

  9. Remote sensing in geology - Wikipedia

    en.wikipedia.org/wiki/Remote_sensing_in_geology

    Remote sensing by satellite also reduces jittering as the sensor is held stable in space and gives accurate data in the absence of atmosphere for terrestrial observations, notwithstanding the strong radiation zone in Jupiter which dramatically limits sensor lifetime. [47] All these promotes future instrumentation and orbit design.
