Tamil Nadu's DGPS improves land surveys, reduces disputes

Tamil Nadu has implemented a Differential Global Positioning System (DGPS) for land surveying, promising accurate digital maps and reduced property disputes. The new system replaces traditional methods, providing landowners with precise digital coordinates and field measurement sketches, improving transparency and convenience. This technology has already issued 100 pattas and is expanding across several districts. The state's DGPS infrastructure, including 70 Continuously Operating Reference Stations, ensures sub-centimeter accuracy, streamlining processes and making land records more accessible.
