State to survey lakes with drones, rovers
Bengaluru: To eliminate the need for repeated surveys of lakes and improve conservation efforts, the state survey and settlement department (SSLR) has switched to high-tech digital mapping, using drones and rovers. This large-scale effort, covering thousands of waterbodies, is expected to modernise how the state tracks its lakes and prevent encroachments. SSLR commissioner J Manjunath said. "We will also mark buffer zones of the lakes during the survey. This digital survey will be helpful to preserve, conserve, and protect the lakes," he added. To manage the data generated from these surveys, the department has developed dedicated software named Web GiS, which will serve as a centralised database for various govt agencies. Each surveyed lake's file will include its exact GPS coordinates, survey numbers, boundaries, extent, ownership (govt department or agency), encroachment details if any, and survey sketches. In the past two years alone, digital surveys were completed for 8,433 lakes using drones and rovers. These details have already been uploaded on Web GiS. Officials estimate only 6,210 lakes remain to be digitally mapped. This final leg of the digital survey is expected to be completed by Dec 31, 2025. by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like Esse novo alarme com câmera é quase gratuito em Ibiraci (consulte o preço) Alarmes Undo Overall, the department has identified 41,849 lakes across Karnataka. Traditional survey methods using chains and compasses had earlier been used to survey 27,206 lakes. The department adopted the digital approach to complete the survey of the remaining 14,643 lakes, of which 8,433 have been digitally mapped. Initially, the Web GiS data will be restricted to govt agencies, but officials say the data will later be made public, enhancing transparency and access.

To avoid disputes, property owners asked to be present during land surveys
Bengaluru: With the state govt accelerating its ambitious land digitisation drive under the National Geospatial Knowledge-based Land Survey of Urban Habitations (NAKSHA) programme, the state survey and settlement department has issued a clarion call: Property owners must be present during survey work or risk ownership disputes initiative aims to digitise and modernise land records in urban areas using high-resolution drone mapping and ground verification to ensure transparency and accuracy. As part of a pilot rollout, 10 urban local bodies (ULBs) — including six city municipal councils and four town panchayats — were selected across the state. These include Bhagyanagara TP and Siruguppa CMC (Ballari), Boragav TP and Gokak CMC (Belagavi), Basavakalyan CMC (Bidar), Kolar CMC, Bagalkot CMC, Chikkamagaluru CMC, Bogadi TP (Mysuru), and Anavatti TP (Shivamogga). Officials have scheduled surveys on Monday and are urging owners or their representatives to be available on site."Once the department issues a draft card of property ownership after a survey, owners could raise concerns or queries about ownership," said J Manjunath, commissioner of survey settlement and land records. "There is a possibility that many owners may approach the department for corrections. If the survey is done in the presence of owners, the number of errors will decrease. So, the department has requested people to be present at their property for survey work."Drones, flown 120 metres above ground, have already completed aerial surveys in eight of 10 areas. The data was used to generate orthorectified radar images (ORI maps) showing every visible structure and feature, from buildings to drainage truthing, or on-site verification, is now underway to match drone data with physical features. "The department had ORI mapping for Kolar, Sirguppa, and Bhagyanagara before the NAKSHA programme was launched. So, the department began ground truthing work for these three ULBs. In the remaining five ULBs, the drone flyover was completed," Manjunath Survey of India provide ORI (origin of replication) maps. Once everything is mapped, the department plans to swiftly complete verification and issue ownership records — making early public participation critical.
