The Great Trigonometric Survey was one of the major projects of India. Its purpose was to survey the entire Indian subcontinent in a scientific way. The great trigonometric system was proposed in 1802 by William Lambton, a British infantry officer under the conservancy of the East India Company. The responsibility of this project was entrusted to the Survey of India under the leadership of George Everest.  On this occasion, the Indian post department launched a set of three Miniature sheets named the Great Trigonometric Miniature Sheet. After that in 1861 it was headed by James Walker. One of the British territories in India included the heights of the Himalayas, Everest and Kangchenjunga.
