The Village of Oak Brook Public Works department performs a wide variety of services to the village including snowplowing and street sweeping. They also maintain various street lights within the village. Prior to the implementation of GIS, Public Works referenced a hand drawn street light atlas of the village. This contained the location of the street lights as well as their id number and the location of fiber optic lines within the village. While this atlas was useful, it did not contain information on each street light for bulb type, ballast, wattage, etc. If a street light needed repair, village staff would have to reference a separate table.

The creation of a street light atlas in GIS allows Public Works staff to locate a particular street light, its wattage and bulb type and ballast using one source in a matter of minutes. This atlas divides the village into areas based on a grid system which allows street lights to be quickly identified and any corrections or changes noted on the atlas sheets. A street light layer is also available in the Consortium's Map Office application which allows access real time street light data.
