GIS is a computerized system of data collection, conversion and analysis that combines layers of digital information to create a comprehensive picture of data. GIS maps can illustrate:
- Land usage
- Infrastructure location
- Public utilities
- Emergency services
- Road type and pavement condition
- Tax rate and other parcel information
- Lot measurement
- Permits issued
- FEMA Digital Flood Insurance Rate Map
A combination of these sets of data can also be used to address a specific issue of interest by showing several layers of data at the same time.
GIS is beneficial for local government, because almost everything it does can be tied to a location. With GIS, members of public works and other government officials can learn a lot about a given location without leaving the office. GIS is a tool that has everyday applications for public works departments. For example, GIS allows questions like, “Who will be affected by this water main break?” and “Where are the nearest valves necessary to stop the flow of water and retain water service to the most people?” all to be answered efficiently through data.
The visualization GIS provides is a powerful advantage. A traditional list of addresses has little impact when compared to a GIS map showing houses with flooded basements or all the passable streets the morning after a major snowstorm. This allows quicker and more accurate decisions to be made.
