Chennai, Nov 11 The Tamil Nadu government on Wednesday released the comprehensive findings of the state’s historic Great Trigonometrical Survey (GTS) stations, in five volumes.
Initiated during the British era by Colonel William Lambton at St Thomas Mount on April 10, 1802, the massive survey spanned nearly 70 years until 1871, according to a press release issued by the government.
The exercise, conducted using theodolite instruments, led to the establishment of multiple GTS stations across India, including various locations in Tamil Nadu. These stations currently fall under the jurisdiction of the Survey of India.
The state government had accorded permission for an integrated approach to systematically identify, survey, map, document, and preserve all GTS stations situated in Tamil Nadu. A key objective of this initiative is to leverage the geo-coordinates of these heritage stations to assist future modern surveying works in the state, according to the press release.
Following extensive joint field surveys by officials from the Survey and Settlement Department and the Tamil Nadu Archaeology Department, the identified stations were completely documented.
The five-volume documentation has been printed and published by the Director of Survey and Settlement. To ensure the long-term protection of these historic stations at the local level, the documents have been officially distributed to all District Collectors and district-level survey officers.
