Remote sensing is the acquisition of information about an object or phenomenon without making physical contact with the object, in contrast to in situ or on-site observation. The term is applied especially to acquiring information about Earth and other planets .
The Land Remote-Sensing Commercialization Act was repealed by the enactment of the Land Remote Sensing Policy Act of 1992. [2] [3] The legislative repeal was passed by the 102nd U.S. Congressional session and enacted into law by the 41st President of the United States George H.W. Bush on October 28, 1992. [4]
In 1965, William T. Pecora, the then director of the United States Geological Survey, proposed the idea of a remote sensing satellite program to gather facts about the natural resources of our planet. Pecora stated that the program was "conceived in 1966 largely as a direct result of the demonstrated utility of the Mercury and Gemini orbital ...
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.
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).
The Remote Sensing Applications Center (RSAC) is a facility of the United States Forest Service (USFS). It receives weather and fire-monitoring data remotely-sensed by satellites, and converts it into maps and reports for the USFS.
It is different from passive remote sensing, the most common type, as the electromagnetic radiation (EMR) is produced by the emitters and they transmit radiation at radio wavelengths (i.e. from around 1 cm to several meters) and sensors use the measured return to infer properties of the Earth's surface. radar remote sensing uses long-wavelength ...
It is the United States' member organization of the International Society for Photogrammetry and Remote Sensing. Founded in 1934 as American Society of Photogrammetry and renamed in 1985, [ 1 ] the ASPRS is a scientific association serving over 7,000 professional members around the world.
