Legacy that spans thro' ages!

Cartography or the science of survey and map making is in the process of a revolution in technology. Technological revolutions are not new in the history of humanity. Cartography has a 2000 year written history from the time of Plato in the Western world. In the East in India, there is a reference to maps and diagrams even from the days of the Mahabharata circa 3100 BC. The Chakras are intricate geometric diagrams inscribed usually on copper plates to attract cosmic energies. But this revolution goes beyond the normal upheavals. It is an epochal revolution.

The first systematic survey of land and settlement operations were conducted during the reign of Raja Raja Chola I (985 – 1011 AD). During the British Period, the Great Trignometrical Survey in India began in AD 1802 when William Lambton laid the baseline of 12 kms from St.Thomas Mount to a hillock called Perambauk which is now called Perumbakkam near Sholinganallur.The world-famous 'Great Arc' Survey which was commenced on 10th April 1802 with the measurements from St.Thomas Mount to Perambuak Hill, closed on the same line after 62 years.
