适用范围: This European Prestandard establishes a schema for spatial referencing using geographic identifiers. It specifies how a system of geographic identifiers is described, and defines the attributes of a location and the contents of a gazetteer of locations. Spatial referencing based on coordinates is outside the scope of this standard. This European Prestandard is applicable not only to digital data, but also to other forms of geographic data such as maps, charts and textual documents.
