Summary

Line-Events for coastal landforms identified in National Agricultural Imagery Program maps and the landforms’ relative vulnerability to horizontal erosion due to sea-level rise ranking are linear-referenced using 1:24,000-scale resolution U.S. Geological Survey National Hydrography Dataset (NHD ) Coastline vector data to create geodata to attribute the conterminous U.S. coastline, Using the Hydrographic Event Management (HEM) tool (https://www.usgs.gov/national-hydrography/tools).), The linear-referenced geodata track along the NHD Coastline in intertidal zones open to oceans, behind barrier coasts in bays, lagoons, and estuaries, and sometimes where tidal currents reach upstream (landward) of the embayed foreshore water bodies. The [...]

Purpose

The purpose for creating the linear-referenced coastal intertidal landform features and associated vulnerability to horizontal erosion geodata is to provide a baseline source that characterizes landforms and stability in conterminous U.S. intertidal zones. The snapshot in time for mapped geodata can be used in analyses and modeling of temporal and spatial intertidal zone change studies used in environmental and ecological management and protection programs.
