DANSK DS/EN ISO 19112 PDF

This International Standard defines the conceptual schema for spatial references based on geographic identifiers. It establishes a general model for spatial referencing using geographic identifiers, defines the components of a spatial reference system and defines the essential components of a gazetteer.
Spatial referencing by coordinates is addressed in ISO 19111. However, a mechanism for recording
complementary coordinate references is included.
This International Standard enables producers of data to define spatial reference systems using geographic
identifiers and assists users in understanding the spatial references used in datasets. It enables gazetteers to
be constructed in a consistent manner and supports the development of other standards in the field of
geographic information.
This International Standard is applicable to digital geographic data, and its principles may be extended to
other forms of geographic data such as maps, charts and textual documents.
