Great Arc has configured an ArcGIS Server Portal environment to provide a centralized repository of Illinois Tollway data that users may use to discover, share and map spatial data. The Illinois Tollway GeoHub organizes the Tollway's spatial data and related tabular data resources into a centralized location for users to access, publish, and share across the lines of business. Individual applications were created using built-in Esri Technology, specifically custom widget development and cartographic integration.
