GIS & Cartography

The GIS / Cartography staff is responsible for tracking ownership of all real property in the County and maintaining a complete set of taxlot maps which adhere to state cadastral mapping standards.  Most documents recorded in the County are reviewed by Cartography to determine if they involve a change in property ownership or property boundary.
