GeoTIFFTM
is a raster map at the 1:50,000 or 1:250,000
scale published by Natural
Resources Canada
and scanned. The collar has been removed
to facilitate seamless navigation. They
are downloadable in a zip file via FTP
protocol.
Topographic
maps produced by Natural Resources
Canada conform to the National
Topographic System (NTS) of Canada.
The National Topographic System provides
general-purpose topographic map coverage
of the entire Canadian landmass. These
maps depict, in detail, ground relief,
drainage, forest cover, administrative
areas, populated areas, transportation
routes and facilities, and cultural features.
They are available in two standard scales,
1:50,000 and 1:250,000. The maps
show a geographic grid (longitude and
latitude) and a Universal Transverse Mercator
(UTM) grid (kilometres). The area covered
by a given map sheet is determined by
its latitude and longitude. Since the
National Topographic System uses a standard
numbering system, knowing the map number
allows you to quickly identify adjacent
map sheets. Under the
NTS, Canada is divided into quadrants
that vary in size depending on dataset
(or map) scale and latitude as described
in the following table.
