Abstract

The marine-terrestrial interface is an environment often mapped as two separate systems. These areas, however, are one dynamic, interactive system. As only a limited understanding comes from treating these separately, seamless onshore-offshore mapping is important in deciphering the dynamic nature of this environment. Few studies have focused on examining methods for incorporating spatially and temporally unrelated datasets to establish baseline topographic data and accurately monitor changes in the shoreface. This study evaluates methods for using Real-time Kinematic (RTK) GPS elevation data along three intertidal structures, a tidal culvert and two rock groins, as tie points to which swath bathymetry and terrestrial LiDAR from north-eastern Cape Cod Bay are attached. RTK GPS elevation data of these structures yield elevations with centimeter-scale accuracy. Swath bathymetry of the intertidal zone yields decimeter- scale relief of the groins and tidal culvert. Terrestrial LiDAR includes decimeter-scale topography of an adjacent area. Results from incorporating these datasets and suggestions for future studies will be presented.
