Geographic Information System (GIS)

 Est. 1990

The mission of the Geographic Information Systems (GIS) program is to engage geospatial technology to enhance the quality of decision-making, support and inform governance, create and delivery of superior digital data, and improve cost-effective delivery of services for Marathon County’s residents, businesses, and government agencies.

What we do

• Administer and operate geospatial software products and systems.

• Create, manage, and maintain web applications that leverage geospatial data for analysis and decision-making.
• Create, manage, and maintain software services that enrich other county systems with geospatial data.
• Produce digital maps of County information.

These services are overseen by the Land Information Office located in the Marathon County Conservation, Planning, and Zoning Department and guided by the Marathon County Land Record Modernization Plan.
