The main characteristic of such maps is the representation of the three- dimensional terrain or relief of the surface of the earth by the use of contour lines.

The elevation of an unlabeled contour line can be determined by knowing the contour interval and looking at adjacent contour … contour interval. n. (Physical Geography) the difference in altitude represented by the space between two contour lines on a map.

A new theory for western boundary sea level The Contour function generates contour lines by joining points with the same elevation from a raster elevation dataset.
The contour interval for the contour lines will be 3 m here. The vertical distance between any two consecutive contours is known as the contour interval. It is kept constant for a contour map to depict the correct topography of the terrain. The survey leader has to decide an appropriate contour interval for his project before start of survey work. The following factors govern the selection of contour interval for a project:
Question is ⇒ Contour interval is, Options are ⇒ (A) inversely proportional to the scale of the map, (B) directly proportional to the flatness of ground, (C) larger for accurate works, (D) larger if the time available is more, (E) , Leave your comments or Download question paper. 2020-04-05 · A contour interval in surveying is the vertical distance or the difference in the elevation between the two contour lines in a topographical map.

Contour lines help geologists in knowing about a topographical region and understanding the topography. A base contour is used, for example, to create contours every 15 meters, starting at 10 meters. In this case, 10 is used for the base contour and 15 is the contour interval.
This means that the change in elevation between contour lines is always 10 feet.

Choose contours, contour intervals now for me the minor interval is 2 and major is 10 by default just change the minor to 1 Make certain the contour is on rebuild automatic. This should help you out, hopefully I didn't screw you up to bad. Sometimes the fast clicking misses a step in explaining it to someome else. Good luck
A base contour is used, for example, when you want to create contours every 15 meters, starting at 10 meters. A contour interval is a vertical distance or a difference in elevation between two contour A contour interval is the _____ for all purposes. a) different. b) same. c) both a and b. d) none of these. Surveying MCQs Set-3 Since the difference in elevation in between every fifth contour line is 100, if we divide that number by the number of contour lines from one thicker contour line to another, which is five, than we get a value of 20, meaning that that is the contour interval.
