The Standard allows the exchange of digital spatial data between different computer systems. It provides a solution to the problem of spatial data transfer from the conceptual level to the details of physical file encoding. Transfer of spatial data involves modeling spatial data concepts, data structures, and logical physical file structures. These regions, based on both spectral and temporal characteristics, can be expected to possess relatively homogenous vegetation types and associations, land use, or mosaics and mixtures of land cover types.

This type of enhancement is commonly done to satellite images and thematic maps utilizing digital topographic data to provide the appearance of terrain relief within the image. Consequently, streams can disappear into subterranean caverns, often not re-emerging until they have traveled underground for a considerable distance. The systematic arrangement of soils into groups or categories based on their characteristics.
