atellite imagery depicts the Earth’s surface at various spectral, temporal, radiometric, and increasingly detailed spatial resolutions, as is determined by each collection system’sensing device, and the orbital path of its reconnaissance platform (Wals. Spatial resolution refers to the smallest measurable area on the ground, the instantaneous field of view (IFOV), that can be sensed in a single pass by a given detector. The scale of a sensing target determines the adequacy of a sensor with regard to its spatial resolution. For instance, the detection of relatively minute features, like glacial flutes or annual push moraines, requires imagery with very high spatial resolution (VHR)  whereas larger and/or more spatially homogeneous targets, like proglacial outwash plains, can be easily mapped using coarser resolution datasets.
