Spatial Data Warehouse (SDW)

Our Web Map Viewers!

A web map viewer of publicly available data sets is provided on behalf of the Government of the Northwest Territories.  The web map viewer provides a means of mapping geospatial information, satellite imagery and aerial photography over the internet. The map viewer can be launched in a web browser; allowing access to the GNWT's Spatial Data Warehouse without specialized software.
