The Delhi government plans usage of drones to conduct the survey of illegal colonies that are waiting for regularization as the Total Station Machine (TSM) system failed to accurately delineate boundaries.

According to the officials, the Revenue department conducted a drone-based survey in a south Delhi colony and the team found this technology faster and accurate. A tender process to hire a consultant for this project will be floated once the policy which is being formulated gets sanctioned from the Delhi Government.

The official said that this is a fast and economical way to conduct a survey as the land records are fed in drones via special software and the drones carry out the survey of a respective area while capturing real-time images of the colony.

The Urban development department hired two private companies to carry out the Total Station Machine (TSM) system [TMS] of 893 colonies in September 2017 and this was estimated to be completed by September 30 this year. For the same, the agencies prepared maps of 566 colonies but the data was found to be inaccurate when the same was verified by the revenue department using revenue records and geospatial maps. Out of these maps, only 62 were authenticated.

According to the sources, the khasra or land records displayed on the geospatial maps were different from the maps that were prepared by the TSM agencies and rectifying the same was a tedious task.

The Delhi High Court has set the deadline of September 30, 2019 to complete the mapping of 1,797 illegal colonies and this will be the task of the revenue department. The Aam Aadmi Party [AAP] promised to regularize illegal colonies in the national capital ahead of the 2015 Delhi assembly elections.
