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.
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.
We mapped substantial migration of the river channel between the City of Winslow and the Navajo Nation community of Leupp; in a human lifetime the river has moved more than a mile across its valley floor.
Description of datasets of AVHRR data available from the EROS Data Center in Sioux Falls, SD in three formats: High Resolution Picture Transmission (HRPT), Local Area Coverage (LAC), and Global Area Coverage (GAC).
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
Technical information on the Aircraft Scanners data set at the USGS EROS Data Center containing digital imagery acquired from several multispectral scanners collected over conterminous United States, Alaska, and NASA aircraft.
