Geographic Information Systems (GIS)
What is GIS?
- A system of software, hardware, data, and personnel that are used to manipulate, analyze, and present information tied to a spatial location.
- It combines layers of information about a place to give a better understanding of a location.
- Often referred to as a "mapping tool"
- Generates maps based upon the collected data
- The possibilities are endless with GIS as it is flexible enough to map anything as long as the data is available
There are two types of maps created by the GIS team: Static maps and Interactive Maps.
- Static maps are generally PDF maps that can be viewed with Adobe Acrobat Reader, a free viewer that can be downloaded from the Adobe website. These PDF maps are a "snapshot in time" and represent information frozen at the time the map was generated.
- An Interactive GIS map is one that allows you, the user, to select one or more of these features and view or print a report containing a detailed list with all the information from that feature's file. To view our interactive maps you will need to download a free map viewer.
- To download this free viewer and access our interactive Parcel Map, click here for first time map users and follow the directions for downloading the free viewer and viewing the map.
- Every effort is made by GIS staff to provide timely and accurate information on this site. If however, you discover an item that appears to be an error, please notify us and we will verify and/or correct the data as needed.
