What is GIS (Geographic Information System)?
A Geographic Information System (GIS) is used to capture, store, analyze, manage, and present spatial or geographical data. It is made up of a few key elements, including hardware, software, data, and the people to maintain it. The Clermont County Auditor’s Office operates our own GIS that allows us to perform many tasks and to provide the taxpayers with useful information. Mapping in an essential function of a GIS. We use our GIS to map the nearly 100,000 parcels of land to support the appraisal of real property in Clermont County. One key piece of data in in our GIS is our aerial imagery, also known as basemaps. Photographs are taken from a specially equipped airplane and then pieced together to make a complete image of the County. Another key piece of data is our parcel lines. The Tax Map Office, located in the Clermont County Engineer’s Office, is responsible for creating and maintaining Parcel lines. They use surveys and other land records to create this layer of information to represent property lines. These lines are representations of the property lines but, are not intended to be legal documents and should not be used in place of the legal documents or fieldwork performed by certified professionals. You should contact a licensed surveyor if you have a property line dispute.
Attribute data from the Auditor’s appraisal system is joined with the spatial GIS data layers. Parcels lines in a map are an example of spatial GIS data, and attached information such as owner name, address, and parcel number would be considered attribute data. GIS is a very effective and efficient problem solving tool which assists the Auditor’s office significantly. The data in our maps is updated on a nightly basis, so you have access to the most current information available.
