A topographic map is a detailed and accurate illustration of man-made and natural features on the ground such as roads, railways, power transmission lines, contours, elevations, rivers, lakes and geographical names. The topographic map is a two-dimensional representation of the Earth’s three-dimensional landscape.

Feb 10, 2021 · Topographic maps produced by NRCan conform to the National Topographic System (NTS) of Canada. They are available in two standard scales: 1:50 000 and 1:250 000. Each map in this system has a unique number, which is a combination of numbers and letters. The area covered by a given mapsheet is determined by its location in Canada.
Jun 25, 2024 · The numbers on a topographic map represent elevation. Each number indicates the height above sea level for a specific point on the map. If a number is inside a line encircling a region, it means that every point on that line is at the same elevation given by the number. For example, if you see a contour line with the number 1,000, it means that ...

Jun 23, 2024 · The numbers on a topographic map represent elevation. If a number is inside a line encircling a region, it means that every point on that line is at the same elevation given by the number. This allows us to visualize the terrain and determine the changes in elevation as we move across the landscape. By understanding these numbers, we can better ...
A topographic survey is typically based upon a systematic observation and published as a map series, made up of two or more map sheets that combine to form the whole map. A topographic map series uses a common specification that includes the range of cartographic symbols employed, as well as a standard geodetic framework that defines the map projection , coordinate system , ellipsoid and ...
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.
