This addendum to volume VIII of the reports published by the office of the great trigonometrical survey of India includes a table of the stations built as part of the survey across Western India and specifically Maharashtra.
The table lists the stations used to conduct the triangulation and their conditions, sometimes 30 years after their constructions. It also lists the surveyors who visited them, including Babu Narsing Das, who repeatedly repaired and checked them. He was one of many Indian contributors to the Great Arc whose name has been left out of the history of the Great Arc, but without whom the entreprise would have been impossible.
The Great Trigonometrical Survey of India was part of the Survey of India initiated by the East India Company to survey the Indian sub-continent during its rule over the territory. The survey recorded topographical information, sounded depths of the navigable waters and recorded land-ownership across the region, but alongside, it set out a complex network to take trigonometrical measures and compute the distances and heights.
Over 70 years, between 1802 and 1871, the survey was conducted with scientific precision and resulted in a variety of scientific advances, from calculating the height of the Himalayan summits to improving the measurement of the curvature of the Earth.
