Remote Sensing Heat Island Effect Glossary Glossary and Key Word List Definition: Remote sensing is a method of visualizing the radiative properties of the Earth's surface using instrumentation mounted on satellites or aircraft. Remote sensing instrumentation measures the radiation reflected and emitted from the earth at different wavelengths, primarily at those wavelengths not absorbed by the atmosphere. Remotely sensed data can be converted to maps showing the visible or thermal properties of an area. Remote Sensing Terms of Environment Glossary and Key Word List Definition: The collection and interpretation of information about an object without physical contact with the object; e.g., satellite imaging, aerial photography, and open path measurements. Remote sensing Watershed Planning Glossary of Terms Glossary and Key Word List Definition: The collection of data and information about the physical world by detecting and measuring radiation, particles, and fields associated with objects located beyond the immediate vicinity of the sensor device(s). Remote Sensing EPA EV-Research-Research Resources-Analytical Methods &Protocols Taxonomy Definition: Science of obtaining information about objects or areas from a distance, typically from aircraft or satellites.Remote sensors collect data by detecting the energy that is reflected from Earth. These sensors can be on satellites or mounted on aircraft. [NOAA National Ocean Service at http://oceanservice.noaa.gov/facts/remotesensing.html]
