Details

Note from Todd: "This polygon layer of GL shoreline was modified by hand to include Saginaw, Tittabawasssee, Maumee, and Sandusky rivers. Outlines of rivers are not precise but were wide enough to allow a continuous connection between pixels for the entire undammed river stretch when the 'rasterize' function is used to produce a raster layer of the GL in QGIS."

Todd's original file name was 'coastline_poly_modified_rivers'.

Filename

shoreline.zip
