Characteristics of Contour Lines
Features of contour lines are helpful in plotting and interpretat
ion of several features in the map.
These characteristics are as given below:
(a) Contour line is a line joining points of similar elevation; hence all points of contour lines have
similar elevation. The elevation of a contour is written close to the conto
(b) Two contour lines of several elevations cannot intersect every other except in case of an

overhanging cliff or a cave (Figure ) refer text book

of Civil Eng
(d) Horizontal equivalent of contours denotes the topography of the area. The uniformly spaced
contour lines imply a uniform slope, although straight and equally spaced contour line denotes a
plane surface. Contour lines closed together de
note steep slope, although a gentle slope is indicated
while contour lines are far apart.
A contour line cannot end anywhere and must close upon itself, through not necessarily
inside the limits of the map.
A set of close contours along wi
th higher figures outside and lower figures inside denotes a
depression or lake, although a set of close contours along with higher figures within and lower
figures outside indicate a hillock

Contour lines cross a wat
er shed (or ridge line) and a valley line at right angles. In that case
of ridge line, they form curves of U
shape across it along with concave side of the curve towards
higher ground, while in case of valley line, they form sharp curves of V
shape across
it within
convex side of curve towards higher ground.
