To facilitate search of our archived topographic raster maps, the CanMatrix - Georeferenced, CanMatrix - Ready to Print and CanTopo collections have been grouped under the following directory: http://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/topographic/.
Here you will find the 6 scales available: 25k, 50k, 125k, 250k, 500k and 1M. This new directory structure allows you to quickly find all the editions/versions/formats available for a specific NTS file. The HTML index has been modified and there is a Readme in the documentation directory ".doc" on the FTP site to explain the new file nomenclature.
Please update your links as soon as possible.
