Airborne Sensors


AS&DMA, NRSC is equipped with state of the art Digital Cameras and Laser scanners to cater to various applications. Both the sensors are integrated with high precision GNSS and Inertial Measurement Systems for generating georeferenced images and point clouds with high degree of accuracy. Integrated Flight Management System of these sensors facilitate accurate and effective coverage of the areas of interest as per the project specifications.

Large Format Digital Camera (LFDC)

AS&DMA, NRSC has a large format digital camera, which can capture images in PAN, Red, Green, Blue and NIR bands. Images can be acquired with GSD of 5 cm with format size of 20,000 x 13,000 pixels. LFDC surveys are very much useful for carrying out various operational activities viz. Large scale Topographic Mapping, High accuracy Digital Elevation Models for volumetric analysis, rail/road planning, 2D/3D Geodatabase generation for e-governance, 3D visualization for planning and cadastral resurvey.
