Mapping land and water resources in India
With rare maps of India including 'Annual Rainfall' map, 'Water Balance' map and 'Land Use' map, the land and the water resource development atlases are excellent sources of information. Amita Bhaduri posted 7 years ago

India’s mapping activity dates back to the Indus Valley Civilization (c. 2500–1900 BCE) as per the famous geographer, Joseph E. Schwartzberg. His work is based on a couple of surveying instruments and measuring rods that were excavated from the Indus valley sites. Our mapping traditions were influenced by Vedic, Tibetan, Islamic and more recently, British cartography.
