20 Resolution and Remote Sensing

Remote Sensing: Resolution

In remote sensing resolution refers to one’s ability to resolve (determine, identify, etc.) what is present in an image.┬áThere are four ┬áresolution types: spatial, spectral, radiometric, and temporal.

Spatial Resolution

Spatial resolution refers to the smallest item that can be resolved visually or spectrally in an image. The extent to which something (of a certain size) can be resolved is directly related to the pixel size of of the image and sensing system

the multivariate nature of resolution is often conflated to spatial resolution.
