Raster-based imagery and terrain variables with wetland/deepwater polygons for select areas in the Great Lakes region

<p>Data was obtained from public sources to produce the aerial imagery, DEM, DEM-derived indices, and other raster variables. Please see that attached &quot;DATA SOURCES &amp; PREP METHODS.pdf&quot; for more information.</p> <p>The shapefiles are comprised of polygons that represent wetland and deep-water classes drawn and attributed by experienced photo-interpreters and are similar to a National Wetlands Inventory (NWI; fws.gov/program/national-wetlands-inventory) product, though these have not been obtained from nor&nbsp;approved by the NWI Program, nor do they&nbsp;exist in the official NWI database.</p> <p>These data can be used for training and validating machine learning and other predictive models for wetland classification.</p>
