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.
The MGDL can still be accessed from links listed below.

The Geographic Data Library catalogs the available GIS
data that the State of Michigan provides for Internet access.
Access to data within
the Library is based upon geographic extent and theme type. For
example, a user may search for data by either county or hydrography.
To search for data, click on the links provided. As you work your
way into the Library, related links between geography or theme will be
available on the right side of this page.
How to use the GIS data:
The geographic information provided through the library
comprises several data formats inherent to GIS software. To
interact with these file types you will need access to software that
supports them. Where possible, notation has been provided to
indicate the file format of these files. All data sets have been
pre-packaged using zip or self-extracting executable file format.
