Great Lakes Aquatic Habitat Framework

GLAHF is a comprehensive spatial frameworkdatabase, and classification for Great Lakes ecological data.

Project Components

1 a hierarchical spatial framework with unique identifiers that link to a comprehensive database
2 a spatial database that consists of available ecological data for the entire Great Lakes basin


3 an integrated river-watershed network – the Great Lakes Hydrography Dataset
4 a hierarchical environmental classification that identifies unique aquatic units across the basin


5 visualization tools & maps including a web-based, publicly accessible geospatial map viewer and decision support tool



Project Funding

The GLAHF spatial framework, database, and aquatic habitat classification have been funded by the Great Lakes Fishery Trust and are housed at the University of Michigan with maintenance supported by the Michigan Department of Natural Resources Institute for Fisheries Research.
