Scope: This document specifies the principles of address data exchange, the content of the exchange, the implementation of the exchange, and the evaluation of the exchange results. This document is applicable to the exchange and sharing of address data among institutions. **Main Technical Content:** 5. Exchange Content 5.1 Spatial and Temporal Reference of Address Data 5.1.1 For planar reference address data, the planar reference should adopt the 2000 National Geodetic Coordinate System or a planar coordinate system based on the 2000 National Geodetic Coordinate System, with units in degrees, minutes, and seconds, and accuracy to the first decimal place after seconds. When necessary, an independent coordinate system approved by law and linked to the 2000 National Geodetic Coordinate System may be used, with units in meters and accuracy to whole meters. 5.1.2 For elevation reference address data, the elevation system should adopt the 1985 National Elevation Reference System, with units in meters and accuracy to whole meters. When necessary, an independent elevation system linked to the 1985 National Elevation Reference System may be used. 5.1.3 For time reference address data, the date should be in the Gregorian calendar, and the time should be in Beijing Time. Units are in days, with accuracy to whole days. 5.2 Address Data Types 5.2.1 General Provisions Address data should comply with the following requirements: a) Address data should have address codes and address names; b) Address data should have accurate spatial location information, expressed using spatial coordinates; c) For different application scenarios, address data have different description methods, divided into standard address data and non-standard address data. 5.2.2 Standard Address Data Standard address data is a standardized address composed of administrative division information, community/village committee information, street/lane information, residential area/vi
