Web Map Services (WMS)

Our Map Services

Below are the three types of web services we offer.  Click to view more details:
- GNWT Operational Layers (Based on ISO-Themes)
- GNWT Basemap Services
- GNWT Mosaic Services

A Web Map Service (WMS) of publicly available data sets is provided on behalf of the Government of the Northwest Territories.

A WMS provides a means of accessing geo-referenced map images over the internet. These can be viewed in a web browser or a geographic Information System (GIS) and incorporated in your own web applications. Further information about WMS can be found on the Open Geospatial Consortium (OGC) web site.

How can I view a WMS?

WMS are designed to allow imagery to be shared over the internet. Applications or software packages can access maps that are hosted on remote servers. This helps with ''mashups'', allowing users to compare and contrast data from a number of sources without having to physically hold the data on their own computers.

There are a number of commercial and free GIS and mapping-type packages in which you can view WMS. For example ESRI ArcGIS Explorer and a number of Open Source GIS and mapping packages.

Please note that the quality of the viewed image may depend on how the software package interprets the WMS.
