Geographic information - Encoding (ISO 19118:2011)

ISO 19118:2011 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".
ISO 19118:2011 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.
ISO 19118:2011 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.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 19118 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics.
This second edition cancels and replaces the first edition (ISO 19118:2005), which has been technically
revised.

ISO 19118:2011(E)
Introduction
This International Standard specifies the requirements for defining encoding rules used for interchange of
geographic data within the set of International Standards known as the “ISO 19100 series”. An encoding rule
allows geographic information defined by application schemas and standardized schemas to be coded into a
system-independent data structure suitable for transport and storage. The encoding rule specifies the types of
data being coded and the syntax, structure and coding schemes used in the resulting data structure. The
resulting data structure can be stored on digital media or transferred using transfer protocols. It is intended
that the data be read and interpreted by computers, but data can be in a form that is human readable.
The choice of one encoding rule for application-independent data interchange does not exclude application
domains and individual nations from defining and using their own encoding rules that can be platform
dependent or more effective with regard to data size or processing complexity. XML is a subset of
ISO/IEC 8879 and has been chosen because it is independent of computing platform and interoperable with
the World Wide Web.
This International Standard is divided into three logical sections. The requirements for creating encoding rules
based on UML schemas are specified in Clauses 6 to 9. The requirements for creating encoding service are
specified in Clause 10, and the requirements for XML-based encoding rules are specified in Annex A.
The XML-based encoding rule is intended for use as a neutral data interchange. It relies on the Extensible
Markup Language (XML) and the ISO/IEC 10646 character set standards.
The geographic information standards are organized within the set of International Standards known as the
“ISO 19100 series”. The background and the overall structure of this series of International Standards and the
fundamental description techniques are defined in ISO 19101, ISO/TS 19103 and ISO/TS 19104.
Users of this International Standard can develop application schemas to formally describe geographic
information. An application schema is compiled by integrating elements from other standardized conceptual
schemas (e.g. ISO 19107). How this integration takes place is described in ISO 19109. The set of
International Standards known as the “ISO 19100 series” also defines a set of common services that are
available when developing geographic information applications. The common services are generally defined in
ISO 19119 and cover access to, and processing of, geographic information according to the common
information model. This International Standard covers implementation issues.
