This application utilizes GIS web sevices provided by the Illinois State Geological Survey.

The ISGS was also instrumental in the collection coordination and managment of the LiDAR elevation data used by the application.

      The application also utilizes GIS web services provided by FEMA to display and query Digital Flood Insurance Rate Map (DFIRM) information.
Site specific links are generated pointing to the FEMA Flood Map Center
More information regarding DFIRMs can be found here: Illinois Floodmaps from the Illinois State Water Survey.

      GIS functional components, base maps (Street Map, Aerial Photo Imagery) and address geocoding are provided by ESRI.

      US Army Corps of Engineers District Boundaries were obtained from USGS
