Parcel data refers to information related to individual parcels of land or properties. This data provides details about the boundaries, ownership, physical characteristics, and other relevant attributes of a specific parcel. It is typically collected and maintained by government entities, such as county or municipal offices, for the purpose of property assessment, taxation, land management, and urban planning.
