WHAT IS REMOTE SENSING?

Remote Sensing is the acquisition and study of aerial photographs and satellite images. With aerial photographs, analysis is typically conducted on the features observed within these images. In the case of satellite images, not only do scientists have a visual record of an area, but also access to additional types of images by analyzing various forms of electromagnetic radiation (infrared, microwave, etc.)

Aerial photographs provide remote sensing scientists with a visual reference by which features can be documented. Specific information on objects seen in an image, such as the size of a particular feature, can also be ascertained through photogrammetry. With two specially coordinated images, a stereo pair can be produced that allows scientists to view a given area in three dimensions, which can also provide valuable information about an area.

Satellite images can allow scientists to view specific types of radiation that are reflected or emitted from a particular object or area. By analyzing this type of data, scientists can recognize patterns and relationships with features and the radiation they reflect or emit and changes in the environment can be observed over time.

Remote sensing is commonly employed to study the environment and its changes over time. Fields such as geology, forestry, oceanography, biology, and agriculture often use remote sensing data to address issues pertaining to the Earth’s environment.
