Description
technical field [0001] The invention belongs to the technical field of computer databases, and in particular relates to a user-customized method, system and storage medium of a geographic entity database. Background technique [0002] Geographic information system is a comprehensive subject, combining geography and cartography, remote sensing and computer science, has been widely used in different fields, and is a computer system for inputting, storing, querying, analyzing and displaying geographic data , it can analyze and process spatial information, in short, it is to map and analyze the phenomena and events that exist on the earth. The implementation relies on the operation of the geographic entity database. In the existing technology, because the geographic entity database often stores a large amount of geographic entity data, and stores different characteristic data of the same geographic entity in a unified manner, all of these lead to slow query speed and low query ...
