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.
Ordering and descriptive information for National Aeronautics and Space Administration (NASA) imagery acquired by the USGS from Gemini, Apollo, Skylab, International Space Station, Space Shuttle, and Shuttle Large Format Camera missions.
Links to Spectroscopy Lab projects to identify and map materials through spectroscopic remote sensing (imaging spectroscopy, hyperspectral imaging, imaging spectrometry, ultraspectral imaging, etc) on the Earth and in space.
This publication (Open-File Report 95-479) is a teacher's guide to two U.S. Geological Survey maps that show gravity and magnetic data in contour form superimposed on a LANDSAT satellite image of the San Francisco Bay area.
The primary goal of U.S. Geological Survey (USGS) Natural Hazards Response is to ensure that the disaster response community has access to timely, accurate, and relevant geospatial products, imagery, and services during and after an emergency event.
We use moderate resolution satellite data to assess live fuel condition for estimating fire danger. Using 23 years of vegetation condition measurements, we are able to determine the relative greenness of wildland vegetation susceptible to burning.
