Using GIS for statistical analysis

​Geographic Information System (GIS) have the capacity to perform
complex analysis of data to reveal patterns or relationships across a
given space. However, the software used to perform these analyses is
often thought of only as a tool for generating maps. While creating a
visual representation of the data in the form of a map is a major
component of GIS, it is not the only way it can be used to assist local
governments in completing their everyday tasks. Generating data
statistics and other analysis results is also a critical function of a
GIS system that can help to consolidate the search for information and
reduce the amount of time spent on a project. For the City of Des
Plaines these statistics have proven to be a vital asset for everything
from gathering basic knowledge of the city systems to compiling reports
for various departments.

An example of a primary use for statistics generated by the city’s
GIS Department is for the city’s annual report. This report documents
various components of the city government, including capital assets,
property values, and general operational information. Related to the
city’s capital, GIS is able to provide values for assets such as miles
of water main, number of fire hydrants, and total street mileage. While
this information is not readily apparent on a printed or digital map, by
working with the underlying data used to generate those maps, the GIS
Department is able to extract vital city information quickly and
efficiently. To gather the same capital asset statistics without GIS
could potentially take hours of searching through various documents or
calling around to several departments to gather the necessary numbers.
With GIS, this information is stored in one central location, making it
more accessible to city departments and reducing potential redundancy by
have information scattered across multiple departments or personnel. By
minimizing redundant data sources, project information and reports can
be generated faster, thereby improving overall employee efficiency.

GIS software is more than just a tool for generating paper and
digital maps for display. Going beyond the visual products it can
produce, GIS is dynamic, layered approach to storing spatial
information, which is often vital to the day to day operations of local
municipalities. By using a robust GIS system, the City of Des Plaines
has been able to help maximize employee and project efficiency by
providing a centralized location to generate various statistics related
to city operations. While a GIS system is not the answer for storing all
relevant city information, it does provide a consistent source location
for making city projects more efficient.
