Finding and Using GIS Data

The AGS Library's Guide to Finding GIS data and working with it for your specific project needs

Milwaukee Open Data

Crime data is now available through the City of Milwaukee Open Data Portal.  Accident data is also available through the Open Data Portal but is not as robust as what was formerly available through the COMPASS platform.  If you need Accident data, please make a data request and the AGSL can request the data directly from the Wisconsin Department of Transportation.

COMPASS details

Datasets: Wisconsin Incident Based Report (WIBR) Group A Offenses, Traffic Incidents, MFD Dispatch Calls, Statistics by District (alderman, police, neighborhood strategic planning), Property, Parcel/Ownership, Census 2010, Liquor License, Open Property Violations, Community Partners, Exempt Properties, Demographic Data Report, Community Housing Survey  


About: COMPASS is a community based collaboration intended to give a clear picture of how problems and opportunities are interrelated by sharing data. It is the City of Milwaukee's crime and traffic accident data portal, providing relevant data that effects public safety.
