Geographic Information System (GIS)

Welcome to the Lake County GIS Department

It is estimated that more than eighty percent of governmental functions are associated with managing information about specific locations or geographic areas. A Geographic Information System (GIS) is a computer system for the input, editing, storage, maintenance, management, retrieval, analysis, and output of geographically referenced information. GIS supports applications such as emergency dispatch, land planning, emergency management and Homeland Security, property appraisal, civil engineering, natural resource monitoring, transportation planning, monitoring crime and accidents, public health and environmental analysis, economic development, census analysis, and many more.

About Us

The Lake County GIS Department was formed in 1999 to create, operate, and maintain a system which will digitally map the county.  Currently the Lake County GIS Department Consists of three fulltime employees. Overseen by a GIS Board consisting of Lake Counties Auditor, Engineer, and a Commissioner. the Lake County GIS Department strives to be a countywide, service driven resource of geographic information for Lake County. We provide spatial data and solutions, which enables our citizens and local government partners to accomplish their goals.

What is GIS?

GIS stands for Geographic Information Systems.  GIS is a system of hardware, software and information that integrates, stores, edits, analyzes and shares geographic data. More information about GIS can be found here.

How accurate are your maps?

The various layers have differing accuracies. The property ownership parcel layer IS NOT SURVEY ACCURATE. This means that you will need to hire a surveyor to define your property’s boundaries. Please email or call us for specifics regarding accuracies.

Where is your office located?

We are located in downtown Painesville, OH in the Lake County Administration Building at 105 Main Street.  The GIS/Tax Map Office is in the lower level.  We are open weekdays from 8:00am to 4:30pm. Please allow us to help you by calling 440 350-5970.

Where can I get data?

We offer GIS data in a few different formats: Downloading GIS data, DVDs, paper maps, and online viewing. Downloading GIS data from our GIS Data Download site is quick and easy, just click here.

DVDs are available at no cost (we encourage the use of our FTP site).  Data formats include: ShapeFiles, DWG and MrSID and JPEG orthophotography.

Paper maps: Printed maps can be obtained in a number of different sizes with varying costs. However, availability of custom maps is dependent upon staff workload.  Prices range from $.25 for 8.5″ x 11″ to $23.00 for a 48″ x 66″ solid fill map. Cash or check only made out to John S. Crocker, Treasurer.
