BLS
Bathymetric Laser Scanning

Where water meets land, changes take place. Close monitoring of these is a necessity. In shallow water, however, surveying from a boat becomes a challenge. This is where Bathymetric Laser Scanning (BLS) is of significant advantage.

Products Get in Touch

The strengths of LiDAR technology in a hydrographic context are the collection of seamless data sets that span the land/water interface, enabling high-resolution surveying of both above and below water surface topology with high efficiency.
