Abstract: Geographic entity data is a real 3D structured and semantic product, and it is the standardized product data of real 3D construction. Based on the analysis of the technical guidance documents of the Ministry of Natural Resources and the relevant research and application of the construction of geographical entities in the pilot cities, and based on the practical experience of building the database of entities in the pilot areas of Zhuhai city, this paper proposes a classification method of geographical entities oriented to city level services, and constructs a geographic entity data set oriented to application services. Taking courtyards, buildings, road entities, etc. as examples, the data organization structure is analyzed in depth, and application research oriented to land spatial planning and urban fine governance is explored.

Key words: geographic entity, data organization, land spatial planning, digital governance, application
