The Cadastral Information Division (CID) is a division of the National Land Commission founded during the Chain Survey in the 1960s. It pioneered land record digitization. CID has led three nationwide cadastral surveys and is the focal point for surveyors in all Dzongkhags. Today, it manages all cadastral surveying, mapping, and provides cadastral maps. CID is upgrading its information system to an international standard coordinated cadastre using advanced GNSS and GIS technology. The National Land Commission aims to establish a more secure land ownership system using modern surveying equipment, strengthening ownership security and the tenure system.
