The corporation has taken the GPS from the state city survey department on rent.

Officials at the VMC said the decision regarding the satellite survey of the river was taken to avoid the disputes related to the boundaries of the river. As Vishwamitri flows from different parts of the city, including residential and commercial areas, it was necessary to adopt scientific methods to decide its boundaries instead of the conventional method of marking physical boundaries.

As per the new system, the boundaries on both sides of the river will be demarcated after considering the GPS maps. The process will reduce the work for the corporation.

“Currently, we are paying Rs 1 lakh to the state government for survey of 16 km as fees for use of equipment belonging to the city survey department. Later, we will finalise the exact rates for per square km survey we carry out,” said executive engineer Dhiren Talpada.

Talpada said that as per the new system, the static and moving equipment would be connected to four different satellites and the images sent by the satellites would be matched with the maps available with the VMC.

By matching both the maps, a superimposed image will be made. It will be the ultimate image for future reference, he said.

“In case of survey done by conventional system, a dispute takes place when someone objects to it. But now, we will not face that problem, as we will be having a satellite image,” Talpada added.

The static mode equipment has been installed at the city survey office in the Raopura area, and covers areas in a 10-km radius on both the sides.
