ASTRALiTe has demonstrated its two-in-one topo-bathy LiDAR system flying on the DJI Matrice 600 Pro UAS during three separate test flight missions.

Designed for topographic LiDAR surveys, the 5kg bathymetric scanning LiDAR system runs on its own self-contained battery, collecting centimetre-level bathymetric data.

In the first demonstration in Colorado, ASTRALiTe integrated its topo-bathy LiDAR system onto the Matrice 600 Pro for two 15 minute flights.

A second demonstration was conducted at high elevation in conjunction with the US Geological Survey in Kremmling, Colorado, at the confluence of the Colorado and Blue rivers. Four flights were conducted with flight times ranging between 10-12 minutes. River transects were made to document volume flow of the two rivers including depth profiles, vegetation mapping and underwater object detection.

A third set of demonstrations was conducted at the University of Hawaii’s Institute of Marine Biology on Coconut Island. Over three days the LiDAR was put to the test on the windward side of the island in conditions that included salt spray and significant surf. In these conditions, Matrice 600 Pro collected near-shore bathymetry, dune, inlet and lagoon profiles, and mapped underwater coral reef structures at centimetre-level resolution.
