The GIS (Geographic Information System) Department is responsible for maintaining and managing geographic data, maps, and other spatial information for the county. The main objective is to provide accurate and up-to-date spatial information to support the county's decision-making processes and to help county staff, residents, and businesses make informed decisions.

The services offered vary, but typically include mapping and spatial analysis, data management and integration, online mapping and data access, and technical support for other county departments. The department provides mapping and spatial analysis services for county zoning, building and planning, emergency management, tax assessment, and other purposes. GIS services are also provided to the general public, including online mapping applications and access to geospatial data.

What is GIS?  GIS stands for Geographic Information System. It's a system used for capturing, storing, analyzing, and managing data and associated attributes that are spatially referenced to the earth. Essentially, it's a technology that integrates hardware, software, and data to provide a comprehensive tool for analyzing and visualizing geographic information.

A GIS allows users to create and display maps and geographic information, analyze spatial relationships, and make decisions based on geographical data. GIS is used in a variety of applications, such as urban planning, natural resource management, crime analysis, and environmental impact assessments.

There are several key data sets which we use including parcel boundaries, road and railroad right of way/center lines, municipal boundaries, soil surveys, land use, topography, hydrology and aerial imagery.  More layers are planned 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 understand property boundaries as they change.  The GIS Department also provides many services such as making custom maps, plat and atlas books, leasing digital data, and helping to resolve spatial/data related issues experienced by others.
