KLCDA takes Isro help to monitor lake condition

GIS expert roped in to handle the software

The Karnataka Lake Conservation and Development Authority (KLCDA), which is short of trained men and lacks support from other government departments, has decided to use technology to monitor the condition of lakes on a real-time basis through satellite images.

Indian Space Research Organisation (Isro) is creating a special geospatial database of all lakes falling under the Bengaluru Metropolitan Region for KLCDA.

“These satellite images will help us know the exact drawings of each lake, the geography, exact dimensions and encroachments. It is aimed at being a helpful tool in the management of lakes,” Seema Garg, KLCDA chief executive officer told DH.

This is the first time such an exercise is being done. Initially, the satellite images will define lakes and their boundaries and alert KLCDA regularly on encroachments. Gradually, the officials in the authority will be able to tap developments on a real-time basis, she said.

Isro is also working on mapping catchment areas, rajakaluves and problem spots. KLCDA will share the data and information with the Bruhat Bengaluru Mahanagara Palike (BBMP) too.

KLCDA officials said this database will strengthen their thin team of 14 people. “There are many instances where we are unable to visit lakes and even monitor encroachment of catchment areas, rajakaluves and water bodies. These satellite images will help us spot any reduction in their sizes on time. We will also be able to store the maps for future reference and for filing cases,” another KLCDA official added.

Data received from Isro will be analysed by KLCDA officials, who will start working on the coordinates provided by Isro. “We have also hired a GIS expert to handle the software. The Isro team is training him on how to study the data and draw inferences,” Seema said.

Rs 32-lakh project

Isro started working on the project to create exclusive data on catchment areas, water bodies and rajakaluves in 2015. The cost of the whole exercise is Rs 32 lakh. The work will be completed in January 2018.
