​​​​​​Ann Arbor Geographic Information System (A2Spatial)

The goal of the Ann Arbor Geographic Information System (A2Spatial) is to develop a central spatial data resource serving all citywide applications and customer service needs.  The A2Spatial service offers users multiple platforms to view and interact with our spatial data, from simple map graphics, PDF's to interactive web based maps like Geocortex which uses live data from our GIS databases.  Please browse the links below to find information of some of our spatial products and tools.

If you prefer you can also download some of the spatial data (and other City documents) for free from our Data Catalog.  The Data Catalog allows you to download ESRI Shapefiles or Google KMZ files of our most popular spatial datasets.  See the link below.
