This dataset includes five ESRI ArcMap shapefiles to provide metadata for those shapefiles. Additional, within the attribute table of each shapefile is a data field titled "SHP_Source" that provides a brief description of the public data sources used to create the shapefile. These data include aquatic non-native species presence in waters of the Laurentian Great Lakes, US and Canadian population for urban areas around the Great Lakes, locations of marinas and ports in the Great Lakes, and data on maritime commerce within the Great Lakes.
