4.1 Spatial datum
The geodetic datum of place names and addresses should adopt the 2000 National Geodetic Coordinate System, with units of degree, minute and second, and accuracy to one decimal place after the second. The elevation datum of the place name address should adopt the 1985 national elevation datum, with the unit of meter and the accuracy to the integer meter1
GB/T39609—2020
Time expression
The time expression related to the place name address should adopt the Gregorian calendar and Beijing time4.3
Primary and auxiliary addresses
When multiple place name addresses refer to the same assignable address object, one of them should be determined as the primary address and the other place name addresses as auxiliary addresses.
Example: When a courtyard, building or household has multiple entrances and exits, the main entrance and exit house number address can be selected as the primary address, and the other house number exit and population addresses can be selected as auxiliary addresses.
5 Classification and Coding Process
5.1 Classification
The geographic codes of place name addresses are divided into two categories: district-based geographic codes and coordinate-based geographic codes: a) The district-based geographic code uses the administrative division code, street and courtyard code, building code, and unit and room code of the place name address for combined coding
b) The coordinate-based geographic code uses the coordinate code and elevation code of the location of the place name address for combined coding. 5.2
Coding Process
The coding process of place name address geographic codes is shown in Figure 1: a)

E-—elevation value of the location of the place name address; the unit and accuracy are both meters (m); gate—rounding operation;
When the elevation value is not provided, ECODE is "00000". Example: The elevation value of the location of a place name address is 250.38m, and its elevation code is 10250.9 Place name address QR code design
Attribute item setting
The place name address QR code attribute item setting should comply with the requirements of Appendix B. QR code generation
（1）
The QR code for place names and addresses should adopt the QR code (GB/T18284), Hanxin code (GB/T21049) or QR code (ISO/IEC18004) and other QR codes. The content is composed of the attribute data items in Appendix B. The data items should be separated by "\||" as the standard separator. For examples, see Appendix C.
3 Information association
The QR code for place names and addresses establishes a one-to-one association with the coded address (Table A.1) and the place name and address geographic code (Table A.2) through the address unique identification code, and establishes a one-to-many association with the auxiliary address (Table A.3). 6

(Normative Appendix)
Place name and address geographic code data model
A.1 Composition of the place name and address geographic code data model B/T39609—2020
The data model of geocodes for place names and addresses consists of GeocodedAddress (coded address class), SupplementaryAddress (auxiliary address class) and GeocodesOfAddress (geocodes for place names and addresses class), see Figure A.1. GeocodedAddress refers to the main address data object containing the geocodes for place names and addresses, and SupplementaryAddress refers to the auxiliary address object, both of which are inherited from the Address class in GB/T356392017. GeocodesOfAddress refers to the geocodes for place names and addresses.
