The Department 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.
GIS technologies are not leveling the playing field but rather leveraging it by adding value, identifying cost savings, and allocating resources more efficiently. GIS technologies are helping people make better decisions.

Core GIS Data Maintenance
Continually mapping and maintaining:
- Tax parcels and subdivisions layer with the cooperation of the Property Appraiser's Office
- Structure locations layer with the cooperation of the Department of Public Safety
- Streets layer, which is critical for routing, geocoding and street maintenance
- Annexation boundaries and city limits layers to assist in the fair and equitable distribution of government services
- Commission districts, hospital districts, voting precincts and government lands layers
- Zoning boundaries which assists County decision-makers
- Addressing Function

 Data Analysis & Modeling
Examples of work:
- ARRA (American Recovery & Reinvestment Act) Station Construction Grant — GIS analysis necessary to aggregate and geocode Fire Rescue incidents. The use of network analysis to locate two new fire stations and their associated 5 & 10 minute response boundaries for a grant application valued at $3.9 million dollars (awaiting outcome).
- 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
- County-maintained roads and population distribution —
Ensures appropriate level of service road maintenance
- Lake County LIDAR/Contour Acquisition Project — Flood Plain Mapping Modeling & Analysis (potential flood plain evacuation modeling); Stormwater Engineering Utilization; Construction Project Design Utilization; and Elevation Data Modeling
- Emergency Operation Center Support —
Provide maps and data to assist first responders in locating, understanding and mitigating emergency situations; and assisting in damage assessment by identifying damaged properties for taxing and funding purposes
- US National Grid (USNG) Map Book Initiative —
This State Comprehensive Emergency Management Plan project will ensure a uniform grid mapping system-US National Grid (USNG), across cities and counties in Florida, and will match the system used by the National Guard, the US Coast Guard and the US military when they are deployed into our state.
- Economic Development Strategic Sites Project – Discovering sites that meet the business communities’ needs to encourage relocation to Lake County.
- 2010 US Census Boundary Data – Partnering with the US Census Bureau to provide current boundary data in anticipation of the 2010 Census.
- GIS/Cartegraph Integration – Merging geometric data with asset management to streamline workflows and better manage county assets.
- Population Projection – Using existing structure location data to discover the population and its distribution across Lake County. This data can be used for districting and proportioning various services and public responsibilities in a fair and equitable, non-biased manner.
- Fire Response Zones Creation-Provide analysis to assist with this critical public service of establishing fire response zones. This assists with the Fire Rescue’s Standard of Cover and Community Risk Assessment.
