James Thomas Walker, CB, FRS (1826-96) was an Anglo-Indian Surveyor General of India. Born at Cannanore, India, he was educated at the military college of the East India Company in Surrey. In 1844 he was commissioned as a second lieutenant in the Bombay engineers and in 1846 was sent to Sindh as an executive engineer at Sakkar. Much of his early career was spent in military operations but, on March 12, 1861, he was appointed superintendent of the great Trigonometrical Survey of India. Over the next two years the last three meridional series in the north of India were completed. His first independent work was the measurement of the Vizagapatam base line, completed in 1862. He next undertook a revision of Lambton's triangulation in the south of India with remeasurements of the base lines. In 1878 he was appointed Surveyor General of India, retaining the office of Superintendent of the Great Trigonometrical Survey. He was a member of the Royal Geographical Society, the Royal Society, and the Russian and French geographical societies. In June 1883 he received an honorary LL.D. from Cambridge.

The Great Trigonometrical Survey aimed to survey the entire Indian subcontinent with scientific precision. It started in 1802 under the auspices of the East India company under infantry officer with some surveying experience, William Lambton. Under the leadership of his successor, George Everest (after whom Mt. Everest is named), the project was made the responsibility of the Survey of India.Upon discovering that accurate instruments could not always be purchased through the standard system of government contract, Everest personally supervised the construction of instruments, getting a maker named Henry Barrow to set up an instrument company in Calcutta. Everest was succeeded by Andrew Scott Waugh, followed by Walker who oversaw the completion in 1871. The survey party at times numbered 700 people. Among its many accomplishments were the demarcation of the British territories in India and the measurement of the height of Himalayan giants like Everest, K2, and Kanchenjunga. The Survey had enormous scientific impact, responsible for one of the first accurate measurements of a section of an arc of longitude and for measurements of the geodesic anomaly that led to the theories of isostasy. While it might be supposed the surveyors were entirely British, native surveyors (called pundits) were made use of in the Himalayas, especially in Tibet where Europeans were not allowed.
