Map Milwaukee GIS Web Services

We currently offer two kinds of GIS Web services to the internet: map services, and geocoding services.

A map service is an internet resource that makes maps, features, and attribute data available to the web.  We publish a number of map services, and many are made easily available to you through our map applications.  Map services not automatically available in an application can be added to any application, or accessed directly using ArcGIS Desktop.

A geocoding service takes input information, such as an address or taxkey, and identifies a point on the map that represents that input.  These web services can also be used by ArcGIS Desktop users.

GIS Web Service Documentation

The documentation about Map Milwaukee GIS web services is a work in progress; always expanding and improving.  For the most current information about our services, use the following documentation:
