Seabed mapping in the near-shore marine environment is as vital as it is difficult. The Geological Survey of Ireland therefore turned to airborne remote sensing to perform bathymetric mapping of Ireland’s most critical shallow-water zones. As part of the Irish National Seabed Survey in 2008, Blom Aerofilms was contracted to deploy its Hawk Eye II bathymetric LiDAR system to create subsurface topographic maps. Data were acquired in three bays that presented significant challenges to traditional ship-borne seabed mapping and in a fraction of the time that surveying by ship would have required.
