Contour maps are very useful since they provide valuable information about the terrain. Some of the uses are as follows:
i) The nature of the ground and its slope can be estimated
ii) Earth work can be estimated for civil engineering projects like road works, railway, canals, dams etc.
iii) It is possible to identify suitable site for any project from the contour map of the region.
iv) Inter-visibility of points can be ascertained using contour maps. This is most useful for locating communication towers.
