Welcome to the City of Ann Arbor's Data Catalog website. This site is part of our ongoing commitment to enhance citizen participation and local government transparency. We are pleased to make City datasets freely available to the public in machine-readable formats.
We expect the Data Catalog site to grow over time as we add additional datasets. By downloading the data, you are agreeing to the Policies and Notices. When creating these datasets the City has been careful to respect privacy and security concerns.
Washtenaw County has now created it's own GIS Data Portal for the community to use when looking for County spatial datasets and web mapping applications.
