The process of detecting and monitoring the physical characteristics of an area by measuring its reflected and emitted radiation at a distance from the targeted area. Remote sensing is used in this thesaurus to refer to methods that are solely or primarily deployed through air or space. Included in this concept are studies of biological populations using remote imaging techniques. Related methods which are used most frequently on the ground (e.g. photography), whether underwater, from airplanes or satellites, are not included in the term remote sensing.
Downloadable data with software showing composite average ocean characteristics (sea-surface temperature and sea-ice concentration). Includes documentation, source code, data, and executable programs for Linux and Microsoft Windows.
A method to create qualitative images of thick oil in oil spills on water using near-infrared imaging spectroscopy data. It relies on the organic absorption features of chemical bonds in aliphatic hydrocarbons. The data cannot give oil volume estimates.
Doppler radar imaging is used for tracking the migration and behavior of bird populations. With the U.S. Fish and Wildlife Service and other agencies, USGS uses this technology to assist decision makers balance natural and industrial concerns
