How was the world mapped and measured before the era of satellites? Did the process of measuring Mount Everest start in any way in Bengaluru?

This is a rebroadcast of Episode 49 with Udaya Kumar PL, as he talks to hosts Pavan Srinath and Ganesh Chakravarthi about The Great Trignometric Survey.

Today, one remnant of this historic technological achievement is under threat: the Sampigehalli Auxilliary Watch Tower near Jakkur is at risk of demolition, but with public effort, it can become a monument that all of us can cherish: https://www.deccanherald.com/metrolife/metrolife-your-bond-with-bengaluru/220-yr-old-structure-under-threat-954629.html

Udaya Kumar started the Inscription Stones of Bangalore group to rescue, revive and rejuvenate the rich written history of Bengaluru. In their efforts, they were responsible for one of the richest archaeological findings of the city in decades in a quiet corner of Hebbal. Currently, he is also Project Director (Honorary) at the Mythic Society, Bengaluru, working on the digital conservation of Bengaluru's inscriptions. Well before this, he got interested in Bengaluru's founding role in one of the greatest scientific achievements of the 19th and 20th centuries, the Great Trigonometrical Survey.
