Land records included tax assessment rolls, survey files, existing paper maps and some deeds where needed. Digitization methods varied. Other parcels were COGO digitized. The purpose of digital tax parcel mapping is to manage the tax assessment system as it relates to land ownership. Other uses of parcel mapping include planning and zoning, conservation, and emergency government applications.
Attribute accuracy is limited primarily to the tax assessment roll link.
The tax parcel GIS layer maintains only the County's parcel ID number. This responsibility lies in the County Treasurer, who also serves as the Real Property Lister. Soon to be included is the State-mandated Parcel ID number. Often, there are 2 or more tabular records for one parcel. The user of the GIS must recognize this and make necessary link action.
