Skip to Resources Section

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.

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 440 350-5982.

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.

Online viewing: If you would prefer to print your own copies from the comfort of your home or business, visit our LakeNavigator site where you can search for specific properties or simply explore the county. We have over thirty layers available 24/7 to anybody with an internet connection.

What coordinate system or projection is the GIS data in?

Ohio State plane coordinate system, North Zone, North American Datum 1983 (NAD83), US Survey Feet.
