Elk Grove Village has recently purchased a GPS (Global Positioning
System) unit to support data collection for its GIS (Geographic
Information System). GPS data collection utilizes the GPS satellites in
orbit around the Earth to calculate the x,y location of the GPS
receiver as well as the time and elevation to a certain degree.
GPS is traditionally used to collect the location of infrastructure
such as manholes, signs, fire hydrants, etc. After the data is
collected it is downloaded, corrected, and then integrated into the GIS.
The correction process involves an automated mathematical adjustment
of the data according to records captured by nearby stationary
Village staff will use this equipment annually to capture
infrastructure from new construction projects and to initiate new
projects which require intense data collection such as a parkway tree
inventory or sign inventory. An added benefit of this device is that it
can be used to locate facilities that may have been buried over time or
that are covered by snow in the winter.
