Free Georeferenced Topographic Map Sheets

So far this year Natural Resources Canada has released over 350 updated or new topographic map sheets and made them available to the public in what they refer to as the CanTopo series. CanTopo is considered the next generation of topographic map sheets that provides quality spatial information that fully complies with international geomatic standards.

The digital maps are considered multipurpose because they can be utilized for a wide range of uses from many different organizations and individuals. Georeferenced versions can also be used with Global Positioning System (GPS) receivers and other digital geographic data sets with various software packages such as Google Earth, ArcMap or Global Mapper. You can also simply print them and use them the way they are, as regular NTS paper maps, just like most of done for years.
