Explanation
Why Correct: Survey of India, established in 1767, is the national surveying and mapping organization of India. It is the sole authority responsible for producing and publishing topographical maps of the country, which depict natural and man-made features such as contours, rivers, forests, and settlements.
Distractor Analysis: Geological Survey of India (GSI) focuses on geological mapping, mineral resource assessment, and geoscientific research, not topographical mapping. Indian Space Research Organization (ISRO) develops satellites and launch vehicles and provides remote sensing data, but it does not publish topographical maps. University Grants Commission (UGC) is a statutory body for the coordination and maintenance of standards in higher education, unrelated to map publication.
Takeaway: Survey of India's headquarters is located in Dehradun, Uttarakhand, and it operates under the Department of Science and Technology, Government of India.
