What are Contour Lines? | How to Read a Topographical Map 101

Feb 5, 2022Contour lines show the elevation above sea level at a given point on your map. Relief shows the difference in elevation between two points on a map. By subtracting the elevation difference between two points you can estimate the relief or elevation change. Shaded relief, or terrain shading, is a technique used to give contour maps a 3D feel.

4. Contours | The Nature of Geographic Information

Drawing contour lines is a way to represent a terrain surface with a sample of elevations. Instead of measuring and depicting elevation at every point, you measure only along lines at which a series of imaginary horizontal planes slice through the terrain surface. The more imaginary planes, the more contours, and the more detail is captured.

Contour Mapping – Meaning, Uses, Intervisibility and FAQs

Contour lines are plane sections of the dimensional graph. In cartography, a contour line is normally called a ’contour’. These lines join points having equal elevated heights, above a predetermined level, normally the sea level. These contour lines often illustrate a contour map, which is the main topic of discussion in this specific content.

What Contour Lines Mean and How to Interpret Them

A contour is a line, very often curved, that is shown on a topography plan connecting points of equal height as related to a datum. The datum may be mean sea level, but more likely in the present day the datum is a geodetic reference. Each contour line represents an interval of vertical elevation, or height, and the spacing of the lines …

Basics of Contour Lines in Topographical Maps

Contour lines are the main characteristics of a map. Contour lines are lines drawn on a map with equal elevation points, so elevation would be constant if you followed the contour line physically. The elevation and terrain shape of the contour lines shows. It is useful because they show the form of the land surface on the map-its topography.
