Web Browsers: If you have popup blocker turned on certain functions in the web application will not
operate properly.
Computer \ Monitor: If you are using an older computer the initial map view maybe slow in loading to your
screen. You may need to install or update older software on your computer to view the web application
properly. Older monitors the data shown on your view screen may appear to overlap or not show up
properly. Maximize the web application to take up your entire screen then zoom in to find a location or use
the (Navigation) – (Search for Parcel) tool to locate a parcel in DuPage County IL.
iPad and MAC users: The DuPageMaps web mapping application was developed in Adobe Flash.
Several features have scale thresholds: (Example: 2FT. Contours, 100\500 Year Floodplain and Planimetric
data.) When you zoom out beyond a certain scale the 2FT. Contours, 100\500 Year Floodplain and
Planimetric data will turn “OFF” on your view screen. The web application has been specifically designed
this way to improve on-line performance. Zoom in to see additional data\information on your view screen.

Norwood.

until you click on a second point or location. Once the second point has been selected the polygon will
appear when you go to click on a third point or location. Note: Fast click point locations and double click to
close\end lines or polygons.
