Parcel Boundaries

 

Parcel boundaries represent the boundaries of a piece of land or an individual property. Through geographical information systems (GIS), counties map such boundaries and compile them into a larger map that includes all properties within the county, a process which occurs regularly as property boundaries are split, combined or modified, ensuring accurate and current data. When combined with specific data attributes about a property, parcel boundary data provides more complete information on each property or set of properties, which can be a very powerful tool.
