Mobile Mapping Systems

Alpha 3D Mobile Mapper

3D laser scanner system for mapping and surveying

The Alpha3D is a high-performance 3D mobile mapping solution that combines a precision laser scanner with a 30MP HDR panoramic camera and state-of-the-art GNSS and IMU technologies.Alpha 3D lidar scanner & mobile mapping system

The vehicle-agnostic system provides fully-calibrated, low-noise high density point clouds for faster, superior data collection and enhanced productivity.

The Alpha3D provides two ports for additional laser scanners as well as a connector for a second GNSS antennas, allowing you to further enhance point cloud accuracy and density as your applications require. The lightweight and compact system is easily mounted on a wide range of vehicles, including USVs and self-driving mapping vehicles.
