In the realm of LiDAR surveying, two prominent methods of positioning have emerged: Simultaneous Localisation and Mapping (SLAM) and Global Navigation Satellite System (GNSS).

Selecting between SLAM and GNSS solutions for LiDAR mapping depends on the specific requirements of the surveying project.

For indoor surveys, GNSS-denied areas, or for rapid, on-the-go mapping, SLAM technology provides an advantage. On the other hand, GNSS-based LiDAR offers native accurate absolute positioning and can benefit surveyors with multi-return capabilities.
