Geographic information - Web map server interface (ISO 19128:2005)
ISO 19128:2005 specifies the behaviour of a service that produces spatially referenced maps dynamically from geographic information. It specifies operations to retrieve a description of the maps offered by a server, to retrieve a map, and to query a server about features displayed on a map. ISO 19128:2005 is applicable to pictorial renderings of maps in a graphical format; it is not applicable to retrieval of actual feature data or coverage data values.
Geoinformation - Web Map server interface (ISO 19128:2005)
Information géographique - Interface de carte du serveur web (ISO 19128:2005)
L'ISO 19128:2005 spécifie le comportement d'un service qui produit des cartes à référence spatiale de manière dynamique à partir d'informations géographiques. Elle précise les opérations d'extraction d'une description des cartes proposées par un serveur et d'interrogation d'un serveur sur les éléments qui s'affichent sur une carte. L'ISO 19128:2005 s'applique aux rendus image des cartes dans un format graphique. Elle ne concerne pas l'extraction d'éléments réels ou de données de couverture.

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 19128 was prepared by Technical Committee ISO/TC 211, Geographic information/Geomatics, from a
base document supplied by the Open Geospatial Consortium, Inc.

Introduction
A Web Map Service (WMS) produces maps of spatially referenced data dynamically from geographic
information. This International Standard defines a “map” to be a portrayal of geographic information as a
digital image file suitable for display on a computer screen. A map is not the data itself. WMS-produced maps
are generally rendered in a pictorial format such as PNG, GIF or JPEG, or occasionally as vector-based
graphical elements in Scalable Vector Graphics (SVG) or Web Computer Graphics Metafile (WebCGM)
formats.
This International Standard defines three operations: one returns service-level metadata; another returns a
map whose geographic and dimensional parameters are well-defined; and an optional third operation returns
information about particular features shown on a map. Web Map Service operations can be invoked using a
standard web browser by submitting requests in the form of Uniform Resource Locators (URLs). The content
of such URLs depends on which operation is requested. In particular, when requesting a map the URL
indicates what information is to be shown on the map, what portion of the Earth is to be mapped, the desired
coordinate reference system, and the output image width and height. When two or more maps are produced
with the same geographic parameters and output size, the results can be accurately overlaid to produce a
composite map. The use of image formats that support transparent backgrounds (e.g. GIF or PNG) allows
underlying maps to be visible. Furthermore, individual maps can be requested from different servers. The Web
Map Service thus enables the creation of a network of distributed map servers from which clients can build
customized maps. Illustrative examples of map request URLs and their resulting maps are shown in Annex G.
This International Standard applies to a Web Map Service instance that publishes its ability to produce maps
rather than its ability to access specific data holdings. A basic WMS classifies its geographic information
holdings into “Layers” and offers a finite number of predefined “Styles” in which to display those layers. This
International Standard supports only named Layers and Styles, and doe
