Abstract: The Bathymetric and Morphological Map data product provides depths of lakes and non-wadeable streams (rivers), sediment and substrate characteristics, as well as the presence or absence, approximate abundance, distribution, and size of underwater flora. High accuracy depth (bathymetric) maps are obtained using a suite of hydroacoustic instrumentation interfaced with a differential global positioning system (DGPS) mounted on a vessel. The Wide Area Augmentation System (WAAS) is a form of DGPS that provides enhanced position accuracy (<3 m). Acou...
