GIS mapping of city: Chandigarh first to use LiDAR technology

Chandigarh, October 19

Chandigarh has become the first city in the country to use light detection and ranging (LiDAR) technology for Geographic Information System (GIS) mapping of the city.

The LiDAR survey data includes high-resolution photograph of the entire city covering around 144 sq km. These high-resolution photographs contain complete details of roads, building, trees, forest, open areas, parks, water bodies and utilities.

This LiDAR data would help in generating the 3D models of the entire city in the form of digital elevation model and digital surface model which would further help department(s) in areas like utility management, population growth, encroachment identification, social economic distribution and traffic management. The Department of Information Technology, UT, organised a training on LiDAR-based GIS mapping of the city.

The training was attended by UT Adviser Dharam Pal, along with senior officials of the UT Administration. The training was conducted by the Society for Promotion of IT in Chandigarh (SPIC) under the aegis of the Department of Information Technology. The training was conducted to sensitise the departments to GIS and LiDAR data and its usage in various departments of the UT for better synergies and effective application of the data. — TNS
