Contour mapping services are becoming very popular as the government and industrial mechanisms are increasingly employing the services of contour mapping systems to control floods, forest fires, real estate planning and development, and a host of other issues.

One of the most widely used of all mapping services is the contour mapping service. Contour mapping deals with the maps which are based on the isopleths of a particular land. An isopleth is a line of equivalent value. It is derived from a Greek word which means ‘same value’. The process of drawing isopleths is known as contouring.

Contour lines on which the contour maps are based, link a number of successive points of equal relief and are used as a tool to depict the topography of a particular place on a map. The height of the ground is shown as above Mean Sea Level (M.S.L.) in feet or meter. It can be traced at any interval as per the requirement. If the contours are traced very near to each other then it represents a steep slope and if the contours are traced far away from each other, a gentler slope is indicated.

The numeric representation of elevation with the use of contour lines is a very important aspect of modern cartography. Contour maps mostly show natural features and man-made structures. Contour maps portray detailed forest cover, drainage systems like lakes and rivers, ground relief like landforms and terrain, populated areas, transportation routes, and facilities like roads and railways, administrative areas, and artificial installations.

Contour mapping services use contour lines to depict the form and the inclination of the particular characteristics of a land since it is quite impossible to depict three-dimensional (3D) features on a two dimensional (2D) medium such as the maps.
