scope:

As for ISO 19111:2003 but with an extension for CRSs associated with moving platforms including associated simple spatio-temporal systems and coordinate operations.
""This International Standard defines the conceptual schema for the description of spatial referencing by coordinates, optionally extended to spatio-temporal referencing. It describes the minimum data required to define 1-, 2- and 3-dimensional spatial coordinate reference systems with an extension to merged spatial-temporal reference systems. It allows additional descriptive information to be provided. It also describes the information required to change coordinate values from one coordinate reference system to another.
