Thalam is back with the next edition of Koota in association with Darter photography.

More than two hundred years ago, the Survey of India embarked on a humongous task of mapping the subcontinent from corner-to-corner, establishing the co-ordinates and creating a comprehensive geographical documentation. One of the greatest measurement exercises made ever, the task took more than 60 years to complete and involved at times more than 700 people working at the measurement sites. The result was a highly accurate geographical data on much of the subcontinent, including establishing the height of Mt.Everest.

Named as the Great Trigonometric Survey (GTS), its first leg charted an east-coast to west-coast path starting at the seashore of Chennai, passing through Bengaluru and ending at the coast of Mangaluru. A few artifacts installed for the epic survey still exist in stages of dilapidation in and around Bengaluru.

Udaya Kumar PL, an engineer and a passionate Bangalorean has conducted an extensive study of the GTS and Bengaluru’s connection with it. In this edition of Koota, Udaya will talk about the fascinating stories behind this incredible exercise.
