Incomplete List of Cook County Property Data Tools

As we continue our work on our Cook County Open Data project, we are exploring already existing tools for interacting with Cook County Government data. Josh Kalov created this directory of ones that may be useful. Over the next several months we will do tutorials and write more information about many of these. As we work to add more raw data and update existing data, it’s important to see and use the vastly helpful tools that the County has invested in to allow residents to learn more about property.
