资源简介：
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). Acoustic images of biota, substrate, and benthic structures are obtained with side scan sonar which are georeferenced and mosaicked in post-processing. The data provided in this file are raw sonar data files with little or no post processing that were collected but not used to develop bathymetric or habitat maps.
