Satellite Imagery: Comparison
Please note this is a comparison between Version 2 by Encyclopedia Editorial Office and Version 1 by Encyclopedia Editorial Office.

Satellite imagery refers to images or image-based data acquired by sensors mounted on Earth-observing satellites to record information about the Earth’s surface and, depending on the sensor and mission, the atmosphere and other environmental phenomena [1][2]. It is a form of remotely sensed information distinguished primarily by the spaceborne platform from which observations are obtained, in contrast to imagery acquired from aircraft, unmanned aerial systems, or ground-based sensors [1]. Satellite imagery can be generated from different types of sensors and observation systems, and the resulting data may differ in spatial, spectral, and temporal characteristics according to the sensor, satellite platform, orbit, and observation design [2]. Satellite imagery may be examined through visual interpretation or processed digitally to derive information about environmental and geographic features [2][3]. Image interpretation involves identifying and analyzing patterns and features represented in the imagery, while digital processing can transform acquired data into corrected or derived information suitable for subsequent analysis [2]. Satellite imagery is used in the study and monitoring of the Earth and in applications involving environmental conditions, natural resources, land characteristics, and geographic change [3][4]. It can also serve as a source for extracting geographic information and producing thematic maps, particularly when satellite-derived information is combined with other geographic data and cartographic methods [4]
