The National Topographic Service divides the surface of Canada into sections 2° in longitude by 1° in latitude, each mapped at a scale of 1:250,000. Each 1:250,000 (eg. 12H) map is divided into 16 maps at 1:50,000 scale (eg. 12H/1, 12H/2, etc.), numbered from the bottom right of the 1:250,000 map in alternating rows. This gazetteer has the relevant 1:50,000 map reference in the second column of each entry.
