Description: The Great Lakes shoreline classification composite dataset is a composite of the environmental sensitivity atlas (ESA) from Environment Canada (EC) and the U.S. Army Corps of Engineers (ACOE) shoreline descriptors. The ESA data ranges in dates from 1987 through the late 1990s, and the ACOE shoreline descriptions are from the 2012 oblique imagery interpetation. The full shoreline class descriptions were reviewed for both datasets and harmonized into 6 common classes, which were further simplified into 3 classes for aquatic habitat classification purposes.

Description: The shoreline sinuosity is the measure of the meandering of a segment of shoreline, where a high value (near 1) means almost straight and a low value (near 0) means highly meandering. The shoreline was aquired from the Great Lakes Hydrography Dataset and is 1:24,000 scale or better. The shoreline was divided into 1 km segments and the sinuosity was calculated by dividing the length of the shoreline segment by the straight line distance between the beginning and end point of the segment.

Description: Data was compiled by many sources over years ranging from 1968-present. The majority of sources are published journal articles with maps that were heads-up digitized. Lake Erie Habitat Task Group data was collected by side scan sonar and proofed with grab samples and underwater video. The shoreline material was extended from the shoreline to the nearshore areas (0 - 30 m of depth) areas of all the Great Lakes except Erie. The shoreline material information is from the the U.S. Army Corps of Engineers (2012) and the shoreline classification from Environment Canada Environmental Sensitivity Atlas (1990s). The shoreline material classification was extended to areas deeper than 30 m for missing data locations in northern Lake Superior. The Euclidean Allocation Tool, part of the Spatial Analyst Extension, was used to extend the shoreline material line feature class values into the nearshore and missing data areas.
