Spatial resolution of remotely sensed imagery A review paper

An important system-performance parameter for remote-sensing systems is the spatial resolution. This term has an imprecise meaning and there are a multitude of different definitions. In this paper, the most important definitions are reviewed and consideration is given to the factors which influence the resolution of a given system. It is concluded that no single definition of spatial resolution can be applied to all systems, nor can spatial resolution alone be used to measure the significant information content of image data.
