GLIN Maps out the Great Lakes

The mission of the GLIN Maps and GIS section is to provide a place where people can find and submit digital data for areas within the Great Lakes region.  The Great Lakes Information Network (GLIN) is a partnership that provides one place online for people to find information relating to the binational Great Lakes-St. Lawrence region of North America. GLIN offers a wealth of data and information about the Region’s environment, economy, tourism, education and more.


This site has four major parts: GIS Datasets, Online Mapping, Map Gallery, and Resources. Users can search for datasets by topic, geographic regions, organizations, or at the GLIN Data Access (GLINDA) Clearinghouse. GIS can be experienced over the Internet through Online Mapping. Map Gallery offers several high quality images that are free for downloading. Resources contains additional information about GIS in the Great Lakes basin. 

GLIN will be home to the Great Lakes Information Network Data Access (GLINDA) Clearinghouse. When completed, the GLINDA Clearinghouse will serve as a node of the Federal Geographic Data Committee’s National GIS Clearinghouse for metadata.

The Great Lakes Information Network Data Access (GLINDA) Clearinghouse functions as a gateway to provide regional geospatial datasets that are current with the National Spatial Data Infrastructure (NSDI) metadata standards.
