The Canadian Geographical Names Service (CGNS) provides an online Open Geospatial Consortium (OGC) compliant web mapping service and is compatible with the Canadian Geospatial Data Infracstructure (CGDI). The CGNS WMS allows for custom cartographic styling through the OGC Styled Layer Descriptor (SLD) Specification. The purpose of CGNS is to gather names that have been approved by the Geographical Names Board of Canada (GNBC) and to make these authoritative records available for government and public use. Ce Service de cartes Web (WMS) du Service canadien de toponymie (SCT) est un service Internet qui donne aux concepteurs d'outils cartographiques OGC, un accès aux toponymes et leurs attributs. Grâce à ce service, les développeurs peuvent accéder à nos données de base les plus récentes. Le sous-ensemble des données du SCT qui est offert pour la visualisation est celui des toponymes officiellement approuvés.

A compliant implementation of WMS plus most of the SLD extension (dynamic styling). Can also generate PDF, SVG, KML, GeoRSS

The Toporama Web Map Service (Toporama WMS) of the Earth Sciences Sector (ESS) at Natural Resources Canada (NRCan) is an Internet service that is intended mainly for online map application users and developers. This service is compatible with OpenGIS® Consortium (OGC) (http://www.opengeospatial.org/) Web Map Service standards and specifications, version 1.1.1. Toporama WMS can be accessed at no cost and without restrictions according to the terms of the licence (http://www.geogratis.ca/geogratis/en/licence.jsp). Registration is optional, but is highly recommended to help users be better known and kept informed, and to improve service. The registration form is available on the GeoGratis Web (http://www.geogratis.ca/) site under the Register to users list section. This service can be used to build a customized map using the best baseline data from the ESS for a given scale. These data are known for being accurate and up-to-date. They are grouped together under 15 information themes developed, depending on the scale, using CanVec 1:50,000, the National Topographic Data Base (NTDB) 1:250,000 and baseline data from the Atlas of Canada.

Tjenesten inneholder topografiske kart i målestokken 1:100 000 til 1:1M. Kartgrunnlaget baserer seg på de offisielle versjonene av S100, S250 og S1000. Dette er en cache-tjeneste.
