What is Contour Interval?
What is Contour Interval? A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map. Usually there are different contour intervals for the different maps. Considering the size of the area to be mapped, contour intervals are assumed. In every map, on the right-hand bottom side, the contour interval is specified. When the contour interval is not specified in the map, it can be calculated as explained in the following sections. The commonly used contour interval is 20 feet for a 1:24,000 map scale. Methods of Contour Interval There are one-of-a-kind techniques of figuring out contour c programming language on a map. Some of the not unusualplace techniques are: Direct size: This includes measuring the space among contour strains and dividing it through the range of contour periods among them. For example, if the space among contour strains is 200 ft and there are 4 contour strains in among, then ...
