In addition, it provides guidelines on how UML should be used to create standardized geographic information and service models. Specifies conceptual schemas for describing the spatial characteristics of geographic features, and a set of spatial operations consistent with these schemas. It treats vector geometry and topology up to three dimensions.
It defines standard spatial operations for use in access, query, management, processing, and data exchange of geographic information for spatial geometric and topological objects of up to three topological dimensions embedded in coordinate spaces of up to three axes. Defines concepts for describing temporal characteristics of geographic information. It depends upon existing information technology standards for the interchange of temporal information.
It provides a basis for defining temporal feature attributes, feature operations, and feature associations, and for defining the temporal aspects of metadata about geographic information.
Since this International Standard is concerned with the temporal characteristics of geographic information as they are abstracted from the real world, it emphasizes valid time rather than transaction time. 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 one-, two- and three-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 coordinates from one coordinate reference system to another. In ISO , a coordinate reference system does not change with time.
For coordinate reference systems defined on moving platforms such as cars, ships, aircraft and spacecraft, the transformation to an Earth-fixed coordinate reference system can include a time element.
ISO is applicable to producers and users of geographic information. Although it is applicable to digital geographic data, its principles can be extended to many other forms of geographic data such as maps, charts and text documents. The schema described can be applied to the combination of horizontal position with a third non-spatial parameter which varies monotonically with height or depth.
This extension to non-spatial data is beyond the scope of ISO but can be implemented through profiles. ISO , Geographic information — Rules for application schema. ISO , Geographic information — Spatial referencing by coordinates.

Many thanks! Geographic information. A draft encoding rule has been developed for the European Noise Directive. That document is not yet online, but some information is in this presentation , and sample GeoPackage files developed according to that draft are in this repository.
