which organisation created the topographical maps of india
Survey of India Great Trigonometrical Survey (1802–1852) was started by British surveyor Col. William Lambton on 10 April 1802 from St. Thomas Mount in Chennai to foothills of Himalayas. 36 inch huge half ton weight Theodolite was used, which took 57 days to measure the 12-km base line. This 5-decade project was completed under Survey General Lt. George Everest in the year 1852. Surveyor Radhanath Sikdar measured Mount Everest in 1852, with a height of 29,002 feet. Modern measurements indicate the height is 29,037 feet. This is regarded as the beginning of systematic topographical mapping in India and the founding of one of the oldest survey and mapping agencies in the world.
Gupta Empire The high points of this period are the great cultural developments which took place during the reign of Chandragupta II. All literary sources, such as Mahabharata and Ramayana, were canonised during this period.[5] The Gupta period produced scholars such as Kalidasa, Aryabhata, Varahamihira, Vishnu Sharma and Vatsyayana who made great advancements in many academic fields.[6][7] Science and political administration reached new heights during the Gupta era. The period gave rise to achievements in architecture, sculpture, and painting that "set standards of form and taste [that] determined the whole subsequent course of art, not only in India but far beyond her borders".[8] Strong trade ties also made the region an important cultural center and established the region as a base that would influence nearby kingdoms and regions in Burma, Sri Lanka, and Southeast Asia.[9][unreliable source?] The Puranas, earlier long poems on a variety of subjects, are also thought to have been committed to written texts around this period.[10]
