Spatial Resolution

Spatial resolution determines the smallest feature visible within a region of an image. Although commonly defined in terms of the Ground Sample Distance (GSD), it is also strongly influenced by the Point Spread Function (PSF) or 2-D image blur and noise. Image blur is often specified as a single parameter such as the Modulation Transfer Function (MTF) at the Nyquist frequency or, more simply, as Relative Edge Response (RER).
