A comprehensive survey and mapping operation utilizing LiDAR technology was conducted from 14 to 16 December 2025 to assess suspected landslide-prone areas in the Balangoda and Belihuloya regions. The operation focused on generating accurate topographic data, identifying landslide risk characteristics, and integrating localized findings with interferometric synthetic aperture radar (InSAR) deformation data to support broader regional risk assessments.

The survey aimed to strengthen disaster preparedness and mitigation efforts by applying advanced geospatial technologies, while supporting long-term planning initiatives relevant to rural areas in Sri Lanka.

The operation was carried out using an M-300 drone equipped with a LiDAR L1 camera, supported by a Real-Time Kinematic (RTK) mobile station to ensure high positional accuracy. Officers and airmen from the Sri Lanka Air Force Geoinformatics Team and the SLAF Drone Team participated in the mission, contributing their technical expertise to the successful execution of the survey. Despite challenging terrain and narrow road corridors in the central mountainous region, the drone operations were conducted with precision to ensure reliable data collection.

Key stakeholders associated with the operation included Senior Lecturer of Sabaragamuwa University, Dr. DR Welikanna, and Wing Commander Indunil Sanjeewa, whose coordination and technical guidance supported the overall objectives of the survey.
