scope:

This part of ISO/IEC 18023 addresses the concepts, syntax and semantics for the representation and interchange of environmental data. It specifies: a data representation model for expressing environmental data, the data types and classes that together constitute the data representation model, and an application program interface that supports the storage and retrieval of environmental data using the data representation model. This part of ISO/IEC 18023 may be applied to the representation of any environmental data including: terrain, ocean, atmosphere, and space. Examples of the representation of terrain data include but are not limited to: physical and administrative boundaries based on characteristics of a planetary surface, terrain phenomena (for example, flooding, volcanic eruption and tectonics), natural features (for example, mountains, canyons and rivers), and artificial features (for example, buildings, roads and vehicles).
