William Lambton | Vibepedia

William Lambton was a British lieutenant-colonel who initiated the Great Trigonometrical Survey of India in 1800, a groundbreaking project that aimed to measure the length of a degree of an arc of the meridian and establish the shape of the Earth. His work laid the foundation for a larger scale trigonometrical survey across the Indian peninsula. Lambton's surveys continued for over twenty years, and he was succeeded by his assistant [[george-everest|George Everest]] after his death in 1823. The Great Trigonometrical Survey of India had a significant impact on the field of geography and surveying, with contributions from notable figures such as [[james-raman|James Raman]] and [[henry-lambert|Henry Lambert]].
