Geographic information — Encoding 4
ISO 15046-18 Cancelled Geographic information - Encoding -



This International Standard specifies the requirements for defining encoding rules for use for the interchange of data that conform to the geographic information in the set of International Standards known as the “ISO 19100 series”.

This International Standard specifies

  • requirements for creating encoding rules based on UML schemas,
  • requirements for creating encoding services, and
  • requirements for XML-based encoding rules for neutral interchange of data.

This International Standard does not specify any digital media, does not define any transfer services or transfer protocols, nor does it specify how to encode inline large images.
