The Office of Information Technology, Geographic Information Services Division, deploys geospatial technologies (discipline of gathering, storing, processing and delivery of geographic information) to share and display data in an easy-to-use format.
Lake County Geographic Information System (GIS) has proven to be integral in a variety of public and private decision-making processes. From siting a new fire station to plotting out future land uses, up-to-date geographical data is a valuable tool. read more »
Responsibilities of the Division include maintaining geospatial data in a consolidated, enterprise-wide system, and supplying County offices with geospatial technologies and assistance with maintaining geographic information. Through expert data analysis, the Division’s professional staff presents geographical data in a creative, productive, cost effective and integrated manner.
The strategic goals of the Division are to create a robust GIS, distribute and share geographic information, encourage data distribution among local and state governments, provide GIS solutions to meet customer needs and enhance GIS-related processes to assist in resource management.

 Data Analysis & Modeling
Examples of work:
- Neighborhood Stabilization Project — Identified areas with the greatest percentage of homes in foreclosure, areas with the highest percentage of homes financed by subprime mortgages and areas where a significant rise in the rate of home foreclosures is likely
- Future Land Use — Geographical data with current and projected populations helps to determine long-term growth and expected service needs
- Zoning and Permitting (ZapMap Application) — Expedites growth management processes
- Millage Code Quality Assurance — Helps to ensure equitable tax liability distribution
- County-maintained roads and population distribution —
Ensures appropriate level of service road maintenance
