Using GIS to realign utilities

​The Geographic Information System (GIS) Department routinely utilizes
its valuable resources to analyze the layout of its current utility
infrastructures. By using the aerial photography that the village paid
for in 2005, the GIS Specialist is able to review utility lines and
structures in their current location and compare them to where they are
located on the aerial photography. Since the utility infrastructure data
was originally created at a time when good aerial photography was hard
to come by, many of this data is not one hundred percent accurate.

Although going to the field to identify the locations of utility
lines and structures is a good method, the ability to quickly access
accurate aerial photography and use it in-house allows for a large
percentage of the data to be verified without leaving the desk. This
allows the village to save time and money for a good portion of the
review process.

It is important to note that using GIS not only can enhance the
integrity of the village’s utility data, but it is also key to recognize
that having this accurate data allows for trustworthy calculations. For
example, when the village conducts a water distribution study, they
rely on the most up-to-date data to submit to an outside consultant so
they can obtain the most accurate results. Moreover, when the Sewer
Department wants to inventory what supplies might be needed for an
upcoming project; they can easily look at the current utility
infrastructure in GIS to get some ideas. Without an accurate foundation,
most analyses cannot provide much value but by using available assets,
it is easy to see how GIS can improve the reliability of utility data
and make it a more trustworthy resource.

The aerial photography and utility infrastructure review process, in
conjunction with the help of GIS technology, helps to answer valuable
questions related to the services that the village provides. As times go
on, the village continues to successfully update their utility data in
order to better understand what they currently own and are in control
of, which helps the village to provide a service that on average is not
always recognized.
