Topographic Map
Topographical maps, also known as general purpose maps, provide detailed representations of geographic features at relatively large scales. These maps showcase essential natural and cultural elements like terrain relief, vegetation, water bodies, cultivated land, settlements, and transportation networks. These maps are prepared and published by the National Mapping Organisation of each country. In India, topographical maps are available in two series: the India and Adjacent Countries Series and The International Map Series of the World.
India and Adjacent Countries Series: The Survey of India was responsible for preparing topographical maps under the India and Adjacent Countries Series until the Delhi Survey Conference in 1937. After this conference, the Survey of India ceased the preparation of maps for neighboring countries and focused solely on creating maps for India according to the specifications outlined for the International Map Series of the World. However, the Survey of India retained the numbering system and layout plan of the abandoned India and Adjacent Countries Series for the new series of topographical maps.
International Map Series of the World: The International Map Series of the World aims to produce standardized maps for the entire globe at scales of 1:10,00,000 and 1:250,000.
