What is the importance of topographical maps? State any two reasons.

Topographical maps are based on accurate survey of the land. They show natural features of the ground like hills elevation, drainage, trees and vegetation as well as man-made features like towns, villages, buildings, roads, canals, railways, power transmission lines and other cultural features in detail. Due to this, two reasons that make them important are:

1. They are used for military purposes.
2. They serve as a guide for travel.
