The Spatial Data Warehouse is a web map viewer of publicly available data sets provided by the NWT Centre for Geomatics.  This web map viewer provides a means of visualizing 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.
