New Hubs and Application Changes

New Application and Data Hubs

MCLIO's applications and GIS data will now be available on two new hubs: Land Information Applications, which is simply the new home for our applications, and GIS Data Downloads which is where you will find all of our data downloads and download related applications. This will replace our Open Data Portal and Data Download Form, which are both being retired. Now you will be able to access the contents of both in one location, as well as additional downloads that were not available before.

These new hubs will soon be available on our updated website.


Application Changes

Two applications will no longer featured on our website: 3D Buildings Viewer and Lidar and Imagery Data Download and Viewer. Here is a breakdown of where to go for which functionality of those apps:

The cached reference basemap and cached street labels will also be retiring in early 2024.  Milwaukee County participates in the ESRI Community Maps program and submits reference data every six months. The cached reference services can be replaced by the following items:
