Application Summary AI generated

This standard specifies the schema for describing coordinate-based spatial referencing systems that include parametric values, such as depth, height, or time, in addition to spatial coordinates. It is applied in geographic information systems (GIS) and geospatial data exchange contexts where a location must be defined not only by its position but also by an associated parameter, such as a sounding depth in hydrographic surveying or a timestamp in moving object tracking.
