چکیده انگلیسی
This study investigates the possibility of combining two shore-based remote sensing techniques, 2D LiDAR and video imagery, to measure 3D intertidal beach topography. The shoreline elevation, measured on a single cross-shore section of the beach by a 2D LiDAR, was combined with the video-derived shoreline contour to finally obtain intertidal beach topography. Vertical root-mean-square error between differential GPS and remotely-derived intertidal beach profiles had an average value of 0.12â¯m, with maximum disparities of 0.14â¯m. Two 3D Digital Elevation Models (DEMs) of the beach produced over two tidal cycles demonstrated the feasibility of shore-based LiDAR-video system of describing in detail the short-term morphological evolution of the intertidal area. Results suggest that the LiDAR-video system can improve the capability of remotely surveying intertidal beach topography providing high quality measurements.
