Michigan GIS Open Data Portal
The Michigan GIS Open Data Portal provides the GIS community with an easy to use single point of entry for all State of Michigan open geospatial data. Use the Portal to browse, search, preview, and download a variety of Michigan geospatial datasets. Browse by category or enter key words in the search box to locate a dataset of interest. You can then read its description to learn more about its authoritative data source and explore attributes before downloading.
The new Michigan GIS Open Data Portal will continue to evolve over time. This new Portal was developed to eventually replace the Michigan Geographic Data Library (MGDL) and we plan to retire the MGDL once all legacy data has been moved over to the new GIS Open Data Portal - http://gis.michigan.opendata.arcgis.com/.
The MGDL can still be accessed from the following link - http://www.mcgi.state.mi.us/mgdl/
