The Atlas of Canada's OGC Web Map Service (WMS)

The Atlas of Canada’s OGC (Open GIS Consortium) Web Map Service (WMS) is an Internet-based service designed to provide developers of on-line WMS compliant mapping tools access to the Atlas of Canada’s base layers.

By using this service, developers will have access to our most current and accurate base data for rendering customized maps. Our OGC-compliant WMS technology is provided free of charge and does not require a contract or license agreement. WMS client software is also required to render maps based on layers obtained from various server sources.

Using the Atlas WMS, there are 25 individual base layers with English titles (a separate WMS exists with French layer titles and descriptions).

The following 25 national scale base layers are currently available through the Atlas WMS:
1. Regions outside Canada (1:2 000 000)
2. Regions outside Canada (1:7 500 000)
3. Regions outside Canada (1:15 000 000)
