What are Remote Sensing Applications (RSA)?
Remote Sensing Applications (RSA) refer to the combination of hardware and software that allows for the processing of information about land, water, or an object, without requiring any physical contact between the sensor and the subject of analysis. The term remote sensing most often refers to the collection of data by instruments carried aboard aircraft or satellites. However, remote sensing is also conducted through a land-based network of environmental sensing stations maintained by a variety of federal, state, and local agencies. Such remote sensing may track weather conditions, measurements of air and water conditions and quality, or other specialty data. Remote sensing applications are commonly used to survey, map, and monitor the resources and environment. Examples of images taken from remote sensing, organized by categories such as agriculture, human dimensions (e.g., environmental impact, population), land surface, and oceans, can be found at NASA’s Visible Earth site, http://
