What is GIS?

A geographic information system (GIS) integrates hardware, software and data for capturing, managing, analyzing and displaying all forms of geographically referenced information.

What does GIS do for Monroe County?

GIS allows users to work with an interactive map to locate and view property maps along with a wide variety of other spatial features, i.e., city limits, streams, soil types, flood zones, etc. Information such as properties assessed over $1,000,000 or properties within 250 ft. of a selected parcel, can be displayed rather quickly on a map or viewed as tabular data. Prior to GIS these types of questions would have been very time consuming to answer.

Can you purchase data and/or maps?

Data and maps are available for purchase, however, a signed disclaimer must accompany the payment. For more information contact the GIS Department by e-mail at Also, please review our GIS disclaimer.

Can maps be mailed or emailed?

We are happy to email map requests.  Please see Map and Plat Email Requests for more information.

Mailing of maps is at the discretion of the GIS Department.

However, you can print your own maps for FREE by going to our GIS website.

Are the parcel boundaries the same as legal surveyed boundaries?

No, the parcel boundaries on GIS and mapping/platting maps are for location purposes only.  In order to obtain legal surveyed boundaries contact a licensed surveyor.
