What is GIS? “GIS is an integrated system of computer hardware, software, and trained personnel linking topographic, demographic, utility, facility, image and other resource data that is geographically referenced.” NASA. A GIS allows multiple features of a map to be related to one another as well as to attribute information in a database, resulting in "intelligent maps."
The Carroll County GIS Department is responsible for maintaining and creating data features within GIS. There are several key data sets which we use including parcel boundaries, road and rail lines, right of way, corporate boundaries, soils, land use, contours, hydrology and orthophotography, with many more yet to be created and utilized in the future. GIS is able to make use of surveys, deeds, or other detailed legal descriptions to better display and update property boundaries as they change. The GIS Department also provides many services such as making custom maps, selling digital data, and resolving spatial/data related issues by facilitating data from the GIS database.
How do I order a GIS map with property boundaries?
Carroll County currently offers two ways to purchase a GIS Map.
- You can call the Assessor’s Office (815-244-0239) to set up a username and password subscription to view and print maps from the website. This is the recommended method if you will have a continued need for access to map and assessment information.
- You can call or email your request to the GIS Office using the contact info provided. Standard maps are produced and delivered for a charge of $10.00 each. This is the recommended method if you will only need a single map and will not need continued access to map and assessment information.
How do I get a copy of my property boundary legal description?
This information will be included on the deed that has been recorded here at the courthouse. You will need to contact the County Clerk and Recorders Office (815-244-0221). For more information visit the County Clerk and Recorders Department Page.
How do I find a survey or property monument?
When a property has been platted or subdivided there are property boundary markers placed in the ground by a surveyor. Older markers are sometimes buried, while newer markers are usually left visible. These markers may indicate a lot corner or a property boundary. There is an important difference. When in doubt these are services a registered land surveyor can assist you with.
What other kind of information does the GIS system contain?
Carroll County GIS also maintains road and railroad center lines, 911 address data, topography, aerial images, many tax district boundaries, city limits, the public land survey system (Townships and Sections), land use data, soil data, important water features and many others.
