By definition, remote sensing is the process of obtaining information from a source without actually coming in contact with the source. But for practical purposes pertaining to this page, this involves gathering data of the Earth by using a variety of sensors onboard satellites and aircraft.
A growing area of scientific study and interest is the environment on local, regional, or global scale and the extent to which human activity affects the environment. Environmental research is similar to other areas of science in that as the answers to some questions are discovered, many more questions are raised which reveal the complexities of the real world. Scientific investigations which are currently underway will answer questions about the ozone depletion, global warming, acid rain, El Nino, etc. but will require anywhere from several years to several decades to obtain definitive answers.
A growing component in the modern environmental investigations is the use of remote sensing techniques to gather and analyze data. There are a wide variety of designs and uses for remote sensing instrumentation that can be deployed on the surface of the Earth, aircraft, or satellites. Remote sensing entails the use of computers, image processing, and geographic information systems (GIS).
The number of applications for which remote sensing can be used is ever increasing. Parties interested in using remote sensing include farmers, oil industries, environmental industries, fishing industries, meteorologists, oceanographers, geologists, cartographers, researchers, and governments. The agricultural industry can use remote sensing to monitor crop stress caused by infestation from insects and disease, to determine effective irrigation practices, and to determine the most effective times and places for planting. Local, state and federal governments are using remote sensing for wildlife studies, global change, vegetation analysis and land use.
