The polygon only needs to be in the final database a single time, but all original attribute information for the different owners needs to be retained. These are assumed to be multiple owners for the same parcel. There are two or more polygons representing a parcel in the original data, however, while sharing the same geometry, they have different attributes.
This flag tells how many duplicates of the parcel were in the original data. These are assumed to be multiple copies of the same parcel, and so duplicates are removed leaving a single polygon, and single set of attribute information in the final database. They have the same geometry and identical attribute information. Removing Duplicate Parcels (PARCELS:DUPLICATE): There are two or more polygons representing a single parcel in the original data.The following five Procedures were performed in this order on the data for each county. It is therefore possible that up to six data quality tests were performed for each county.A parcel to which none of the procedures was applied was also tested to make sure all of the normalized attributes in the original data were correctly transferred to the final dataset.
For each of these procedures applied in a county, one test parcel to which a process was applied was selected and tested to ensure the procedure was applied correctly. The data for each county was tested to see whether or not these five procedures were applied.While processing and normalizing the data for each county to a standardized statewide dataset, five possible procedures could have been applied: Removing Duplicate Parcels, Flattening Stacked Parcels, Creating Multipart Parcels, Removing Duplicate Names, and Removing Duplicate Taxrolls.Detailed information about the database schema can be found on the technical documentation page. The normalized Statewide Parcel Database consists of multiple related tables, relationship classes and lookup tables. Property Information / Mapping Coordinator
