This groups of standards is also built on the domain reference model of ISO 19101-1:2014 Geographic information - Reference model - Part 1: Fundamentals, but, in contrast to the data model standards, which are focused on individual features and their characteristics, these standards are focused on the description of data sets containing information about one or, typically, many feature instances.

  • ISO 19111:2007 Geographic information - Spatial referencing by coordinates. Geographic information contains spatial references which relate the features represented in the data to positions in the real world. Spatial references fall into two categories: those using coordinates; and those based on geographic identifiers. ISO 19111 provides a schema for describing the coordinate reference systems used to relate the position of geometric primitives to the earth or another object.
  • ISO 19112:2003 Geographic information - Spatial referencing by geographic identifiers. Geographic information contains spatial references which relate the features represented in the data to positions in the real world. Spatial references fall into two categories: those using coordinates; and those based on geographic identifiers. ISO 19112 provides a general model for spatial referencing using geographic identifiers, as well as specifying the components of a spatial reference system and the essential components of a gazetteer.
