Natural Resources Canada提供的免费的等高线地图(50K)，这个下载链接是PDF格式(40"X28")

我们hiking的地方大多在这个范围内：
ftp://ftp2.cits.rncan.gc.ca/pub/cantopo/50k_pdf/092

TIF格式:

先找出要去地方的位置是在哪一张NTS Map上（最容易的方法是看103 hikes,Bivouac等等的资料上的注明），比如，Rainbow lake在NTS Map: 092.J.03上，就在这里下载
ftp://ftp2.cits.rncan.gc.ca/pub/cantopo/50k_pdf/092/j/

比如Vedder Mountain在092.G.01这张地图里，这里找相应下载
ftp://ftp2.cits.rncan.gc.ca/pub/cantopo/50k_pdf/092/g/

再比如Wendy Thompson Hut在092.J.08这张地图上，这里下载

Vector Indexes of the National Topographic System(NTS) of Canada

Abstract
Topographic maps produced by Natural Resources Canada conform to the National Topographic System (NTS) of Canada. Indexes are available in three standard scales: 1:1,000,000, 1:250,000 and 1:50,000. The area covered by a given mapsheet is determined by its latitude and longitude. 1:1,000,000 mapsheets are identified by a combination of three numbers (e.g. 098). 1:250,000 mapsheets are identified by a combination of numbers, and letters ranging from A through P (e.g. 098C). Sixteen smaller segments (1 to 16) form blocks used for 1:50,000 mapping (e.g. 098C03).

Purpose
The standard NTS numbering system shown on the NTS Index Grid allows users to locate a map and determine its coverage or quickly identify adjacent maps. These data indexes can be combined with any other digital data.
