Great Lakes and St. Lawrence River Medium Resolution Vector Shoreline Data

摘要

Digital medium-resolution vector maps of the Great Lakes and St. Lawrence Rivershoreline are compiled by the Great Lakes Environmental Research Laboratory (GLERL), and translated into multiple common formats including the Topological Vector Profile of the Spatial Data Transfer Standard (SDTS), to enhance data accessibility. The vector maps include a three tier classification representing the shoreline geomorphic nature, the extent of shoreline protection, and the nearshore subaqueous geomorphic nature. Metadata, documented in accordance with SDTS specifications, accompanies the digital maps.
