Karnataka to deploy 5,000 GPS rovers to transform land survey system

Dharwad: In a major technological overhaul, the Karnataka govt has launched an ambitious plan to modernise its land survey system by replacing the nearly 200-year-old chain-and-staff method with advanced GPS-based rover devices.The revenue department has already procured 465 rover units and plans to distribute a total of 5,000 devices to surveyors across the state. Revenue minister Krishna Byre Gowda said the traditional system, in use since 1806, will soon be phased out. Agencies are being selected to supply the remaining units.
The rover devices are integrated with Continuous Operating Reference Stations (CORS) and provide coordinates with a margin of error of just 1–2 centimetres. Officials say the technology is nearly 20 times faster than conventional methods. Surveying 400 acres of land, which earlier took up to 20 days for two surveyors, can now be completed in a single day. A small land parcel that required nearly five to six hours for measurement and map preparation can now be surveyed and mapped within 10 minutes.Survey and land records commissioner J Manjunath said 465 surveyors are already equipped with the devices. The rovers will be deployed primarily in urban areas and will also verify digital sketches generated through recent drone surveys. They will connect to 41 CORS stations across Karnataka to ensure high-precision mapping.The reform comes amid growing demand for land surveys and mounting delays. The department receives over 100 applications daily for property division, layout approvals, road works and tank mapping. Applicants using the Bhoomi portal have often had to wait months due to staff shortages and adverse field conditions. Delays have triggered protests by farmers in several North Karnataka districts, including Dharwad, Gadag, Bagalkot, Koppal and Vijayapura.Deputy director of survey and land records Mohan Shivannavar said the GPS-based system aims to ensure near 100% accuracy, reduce manual errors and resolve long-pending land disputes. Traditional chain surveys required significant manpower and were prone to delays.Under the new system, digital ‘C' copies of land maps will be issued more quickly. Updated records will include QR codes, allowing landowners to access tamper-proof property details instantly, improving transparency and reducing litigation.To strengthen manpower, the government has issued a notification to recruit 750 new surveyors. Although recruitment faced delays due to internal reservation issues, the minister assured that appointment orders would be issued soon.The department had earlier experimented with Digital Global Positioning System (DGPS) technology, but rover devices have proven faster and more efficient. Similar rover-based land surveys are already operational in Haryana, Telangana, Andhra Pradesh, Kerala, Maharashtra and Madhya Pradesh.With GPS-enabled rovers, drone integration and digital land records, Karnataka's revenue administration is set for a major transformation aimed at delivering faster, accurate and transparent land survey services to citizens.
