Details about the location (or physical) address of the place are represented in six attributes:
street- Data Dictionary
suite- Data Dictionary
city- Data Dictionary
state- Data Dictionary
postal_code- Data Dictionary
country_code- Data Dictionary
When a place receives mail at a different address from where they are physically located, we collect a mailing address. Because places can receive mail in different states than they are physically located, mailing address is represented in four attributes:
mailing_address- Data Dictionary
mailing_address_city- Data Dictionary
mailing_address_state- Data Dictionary
mailing_address_postal_code- Data Dictionary
Places are assigned latitude and longitude coordinates in two attributes:
geo_match_level attribute to determine the precision level of the coordinates.
Also known as "Parcel" level, a rooftop precision level represents actual data where the latitude and longitude coordinates plot in the center of the parcel boundary associated with the physical address. Typically these points are at the rooftop of the building.
Also known as "Site" level, interpolated rooftop coordinates are estimated through a proprietary interpolation algorithm using known street segment ranges with the address numbers.
For example, if a street segment is 100 to 200 Main Street and there are five known addresses on that side of the street, the coordinates are evenly spaced out in fifths along that street segment.
Address parity is used to determine which side of the street an address falls. If the address falls on the left side of the street, then the coordinates are shifted to the left. If it is on the right side of the street, the coordinates are shifted to the right.
ZIP+4 Centroid coordinates are plotted at the geographic center of the 9-digit ZIP+4 area, which is about the size of a city block.
ZIP+2 Centroid coordinates are plotted to the geographic center of the 7-digit ZIP+2 area, which is usually the size of a neighborhood or business district.
ZIP Centroids are plotted to the geographic center of the 5-digit ZIP area.
