Tamil Nadu uses global positioning system to survey land

Tamil Nadu has started using global positioning system and electronic total stations to survey land.

The survey using the global positioning system and electronic total station was conducted on a pilot basis in one village initially and then using the experience gained, the scheme had been extended further.

Modern surveying is now in progress in Chennai, Coimbatore, Tiruppur, the Nilgiris, etc.

The department had proposed to initially introduce modern survey in the newly-created municipal areas for which land records had to be prepared afresh by adopting the town survey system. Accordingly, preliminary work has been started in 11 municipalities so far.

It had also been decided to set up eight modern survey scheme offices with all facilities like computers and accessories, plotters and mapping software.

Under the National Land Records Modernisation Programme, action has been pursued for the creation of land record management centres in the 10 taluks of Kancheepuram district and 11 taluks of Thirunelveli district besides setting up NLRMP cell at the Survey Training Institute, Orathanadu.

The NLRMP envisages online, automated mutation of land records through integration of registration process with the land records maintenance system, to facilitate online delivery of ‘conclusive title’.

Digitisation of field measurement sketches is under progress using ‘Collabland’ software developed by the National Informatics Centre. For this purpose, computer cells have been created in 29 districts and 20 computers and peripherals have been installed in each district. The digitisation is done through the staff of the survey department. So far, around 1.3 million field measurement sketches out of around 5.3 million FMS have been digitised,
