In physics and geosciences, the term spatial resolution refers to distance between independent measurements,{{Cite journal|title=Synthesis of multispectral images to high spatial resolution: a critical review of fusion methods based on remote sensing physics

While in some instruments, like cameras and telescopes, spatial resolution is directly connected to angular resolution, other instruments, like synthetic aperture radar or a network of weather stations, produce data whose spatial sampling layout is more related to the Earth's surface, such as in remote sensing and satellite imagery.
