COVER
A surface model of a combined multibeam bathymetric and aerial survey. The site is a 1-square-kilometer coastal inlet situated in the north of Scotland. The survey was carried out utilizing a R2Sonic (Austin, Texas) 2024 MBES and a Trimble (Sunnyvale, California) UX5 drone. The survey was processed within Hypack (Middletown, Connecticut) HYSWEEP software and surveyed by Gordon Campbell from Aspect Land & Hydrographic Surveys Ltd. (Irvine, U.K.).
