Spatial resolution refers to the level of detail that can be seen in an image or data set, typically in the context of remote sensing or imaging technologies. It is determined by the size of the individual pixels or data points that make up the image, with higher resolution meaning smaller pixels and thus more detail. Spatial resolution is important in a wide range of applications, from monitoring land use and environmental changes to medical imaging and archaeological research. Improvements in spatial resolution can lead to better accuracy and more precise analysis in various fields.
