Marine Services :: Mobile Vessel Laser Scanning
DEA Marine Services Division uses a vessel-based laser scanner with a measurement rate of approximately 8,000 points per second interfaced with the vessel position and motion reference system.
A digital SLR camera with a fixed, calibrated lens that is aligned to the scanner with a precision mount allows georeferenced imagery to be collected concurrently with the scan data. Multibeam bathymetry can also be obtained alongside the scan data, so that DEA can collect a very dense dataset—from the seafloor to the top of bank—in one pass. Combining mobile laser scanning with multibeam hydrography enables the generation of a fully integrated hydrographic and topographic digital terrain model.
DEA utilizes several static topographic scanners as well as mobile terrestrial systems for high-definition 3D laser scanning, asset management, and infrastructure mapping.
