History
The history of the Survey of India dates back to the 18th century.[5] "First modern scientific survey of India" was undertaken by John Mather in 1793–96 on instructions of Superintendent of Salem and Baramahal, Col. Alexander Read. The present Dharmapuri district, Krishnagiri district and North Arcot in western Tamil Nadu were then called Baramahal.[6]
The
Organisation
The Survey of India, headquartered at Dehradun, Uttarakhand, has 18 geospatial divisions ranging from the prediction of tides to aerial survey. It has 23 Geo-spatial Data Centers spread across India, each catering to the respective administrative area. Surveyors are the back bone of Survey of India. Appointments to Group 'A' Civil Stream posts in the Junior Time Scale (Dy Supdtg Surveyor) in Survey of India are made on the basis of competitive

Maps
The Survey of India publishes maps and the unrestricted category maps can be obtained from its several Geo-spatial data centers. Restricted category maps require due approval from government authorities. Many other rules govern the sale and use of Survey of India maps. Only an Indian citizen may purchase topographic maps and these may not be exported from India for any reason.[7] On 15 February 2021, the Government of India announced changes to the country's mapping policy which frees up lot of earlier restrictions related to mapping.[8] A list of restrictions proposed is published by DST for comments by 30 July 2021.[9]
