Contour Line
A line connecting points of equal elevation, used in terrain analysis and visualization.
How do you define a Contour Line?
On a map, a contour line is a line that joins locations of equal elevation above a given reference level, typically mean sea level. These lines aid in the two-dimensional visualization of the terrain by indicating the elevation and form of the land surface.
Topographic maps use contour lines to depict slopes, hills, and valleys. The distance between lines shows how steep the terrain is; steep slopes are indicated by closely spaced lines, whereas mild slopes are indicated by widely spaced lines.

Curved lines that join places of equal elevation on a map are known as topographic contour lines. They aid in two-dimensional terrain visualization by displaying the land's height, slope, and contour.
The shape and slope of the terrain are represented by contour lines, which are curved lines on a map that join points of equal height in a GIS. In disciplines including surveying, engineering, and environmental studies, they aid in the visualization of landforms, the detection of elevation changes, and analysis.
A map's contour lines, which show locations of equal elevation, aid in illustrating the height and form of the terrain. Steep slopes are shown by closely spaced lines, whilst mild slopes are indicated by widely separated lines. Elevation numbers indicate height above sea level, while concentric circles frequently depict hills or depressions.
Using contour lines connecting places of equal elevation above sea level, an elevation contour map depicts the Earth's surface. It facilitates the visualization of elevation variations, slope, and terrain contour.
