Cook County Board President Toni Preckwinkle announced that Cook County is upgrading its mapping system to better improve efficiency and services to residents and facilitate graphic representations of what would otherwise be available only as statistical data. Previously, only County employees who were experts in Geographic Information Systems (GIS) could create interactive, online map applications. Now any employee who knows how to use a simple spreadsheet that includes addresses can create an interactive web mapping app with ArcGIS Online (AGO). One of the first web maps to come out of Cook County AGO is the “History of Municipal Incorporation in Cook County.” This educational “story map” presents a written history along with historical images and documents on the left side of the screen. Another new AGO map, which helps the County operate more efficiently, is the Early Voting Sites map created by the County Clerk’s office. The Clerk’s office uses the map to route volunteers to the early voting site closest to them that is most in need of their help. The application keeps track of language skills and other special information per early voting site, which helps the Clerk’s office send volunteers where they are needed most. County employees and the public will still have access to existing web mapping applications; however, now County employees will have the ability to create their own custom web apps to analyze data, streamline workflows or share information with the public.
