Contour lines across ridge or valley lines at right angles.

Flat ground is indicated where the contour are widely separated and the steep ground where they run close together.ģ. Contour Interval and Horizontal Equivalent:Ģ. Thus a contour map serves the purpose of both, a plan and a section. A contour map therefore, gives an ides of the altitudes of the surface feature as well as their relative positions in plan. The process of tracing contour lines on the surface of the earth is called contouring and the maps upon which these lines are drawn are called contour maps. And if the level of water is raised successively by 1 m, the successive shorelines represent 61, 62, 63 m contours and so on. Supposing a depression is partly filled with water and R.L of the water surface is say 60 m, then the shore line of this water represents 60 m contour. This means every point on a contour line has the same altitude as that of the assumed intersecting surface. Definition of Contour:Ī contour or a contour line may be defined as the line of intersection of a level surface with the surface of ground. Contour Interval and Horizontal Equivalent 3.
