Scope: This standard defines the conceptual model based on coordinate space reference, and can also be extended to space-time reference. It specifies the minimum data required to define 1-dimensional, 2-dimensional and 3-dimensional spatial coordinate reference systems and coordinate reference systems extended to space-time coordinate references, allowing Provides supplementary explanatory information and also describes the information needed to change coordinates from one coordinate reference system to another. In this standard, the coordinate reference system does not change with time. For coordinate reference systems defined on moving platforms (such as automobiles, ships, airplanes, and spaceships), when transformed to a ground-fixed coordinate reference system, time elements can be included. This standard applies to producers and users of geographic information. Although it applies to digital geographic data, its principles can be extended to many other forms of geographic data, such as maps, charts, and text files. The mode described in this standard can be applied to the combination of plane position and a third non-spatial parameter, which varies monotonically with elevation or depth. Extensions to non-spatial data are beyond the scope of this standard, but can be achieved through dedicated standards.
