Who publishes the topographic maps of India?

Topography concerns the shape and character of the Earth's surface and maps were amongst the first artifacts to record these observations.

In modern mapping, a topographic map or topographic chart is a type of map characterized by large-scale detail and quantitative representation of relief, usually using contour lines (connecting points of equal elevation), but historically using a variety of methods.

The Survey of India is responsible for all topographic control, surveys and mapping of India.
