A spatial identity coding method of geographic entity based on spatial loca-tion
Basic geographic entity spatial identity code is an identification code suitable for the management and application of basic geographic entities,which has the characteristics of achie-ving global exclusive identification,unique identification,and information association sharing of basic geographic entities.This article proposes a geographic entity spatial identity code consisting of four parts:location code,category code,time code,and sequence code,combined with the col-lection and production of geographic entities in a certain prefecture level city.It is a 29 digit mixed code geographic entity spatial identity code,and the coding component level expansion is carried out in the case of multiple entity entities,so as to meet the requirements of"one code polymorphism"and on-demand assembly in the construction of geographic entity collection.
