Great Trigonometric Survey

The Great Trigonometric Survey was a project of the Survey of India from the early 1800s till the end of the 19th century. It was piloted in its initial stages by William Lambton, and later by George Everest. Among the many accomplishments of the Survey were the demarcation of the British territories in India, and the measurement of the height of the Himalayan giants - K2, Kanchenjunga and Everest. The Survey had an enormous scientific impact as well, and was responsible for the first accurate measurement of a section of an arc of longitude, and measurements of the geodesic anomaly.
