The Survey of India is India's central engineering agency in charge of mapping and surveying. Set up in 1767 to help consolidate the territories of the British East India Company, it is one of the oldest Engineering Departments of the Government of India. The Survey of India's distinguished history includes the handling of the mammoth Great Trigonometric Survey under William Lambton and George Everest. Its members are from Survey of India Service cadre of Civil Services of India.Survey of India publishes maps and the unrestricted category maps can be obtained at very reasonable prices from its several Geo-spacial 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. Indian mapping and map distribution policies are currently under review and may be changed.
