Aerial Services & Digital Mapping

Operational Projects

NRSC has executed several projects to generate high resolution geospatial data base using airborne sensors like aerial camera, airborne laser scanner (ALS), Synthetic Aperture Radar and ground based survey equipment like GPS. Some of the important projects are highlighted below -

Disaster Management Support
