HELIMAP: Rapid Large Scale Mapping Using Handheld LiDAR/CCD/GPS/INS Sensors
on Helicopters 25.09.2005

The HELIMAP is a portable mapping system for quick helicopter deployment. It integrates high accuracy navigation sensors (GPS/INS) with Airborne Laser Scanner (ALS) and high-resolution digital (CCD) camera. The system is operated from the side of a helicopter and its unconventional design offers several conceptual advantages in comparison with other systems: quick installation (minutes), no need of recalibration after installation, possibility to map vertical or horizontal features with an optimal geometry and maintaining optimal flying parameters for camera and laser sensors at the same time. The products are high-resolution (<1m2) / high precision (~0.1m) DSM/DTM and ortho-rectified image (<0.05m/pixel).
