Which of the following is NOT one of the three contents of parcel data?

The correct answer is that Property Ownership Certificates are not one of the three contents of parcel data. In the context of parcel data, the primary components typically include assessment data, parcel attribute databases, and property map data.

Assessment data provides information on the value of the property for tax purposes, while the parcel attribute database contains specific information about each parcel, such as size, zoning, and land use. Property map data visually represents the geographical information of parcels, often including boundaries and dimensions.

Property Ownership Certificates, on the other hand, are legal documents that prove ownership of a property. While they are critical in the context of real estate transactions and ownership rights, they do not fall under the technical categories that define parcel data itself. This distinction helps clarify the types of data used in land management, taxation, and urban planning.
