What is a contour interval on a topographic map
. Contour interval is the actual change in elevation represented by the space between two adjacent topographic rings. A contour map is a map illustrated with contour lines for example a topographic map which thus shows valleys and hills and the steepness or gentleness of slopes. Usually there are different contour intervals for the different maps. Contour lines are spaced by contour intervals and represent areas on land that lie the same distance above sea level taken to be zero feet 0 by convention.Contour lines show elevation and the shape of the terrain. A contour map consists of contour lines for a given geographic region. It is the vertical distance by which various contour lines are separated from each other on a topographic map. These elevations are chosen to be evenly spaced vertically.
A contour interval is the difference in elevation between various contour lines. This quiz is incomplete. This quiz is incomplete. A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map.

Topographic maps contour interval draft. This vertical spacing is referred to as the contour interval. Contour lines are lines drawn on a map connecting points of equal elevation meaning if you physically followed a contour line elevation would remain constant. The difference is usually represented by each contour line on the map.
Contour maps offer a deceptively high amount of information when analyzed skillfully and can be accessed on command using online mapping sites and applications. For example the maps on the previous page used a 10 ft contour interval. A contour interval in the survey is the vertical distance or the difference in elevation between the two contour lines on a topographic map. Co ntour li nes are the greatest distinguishing feature of a topographic map.
For example if there is a contour interval of 20 feet each topographic line. 9 questions show answers.
