Based on the analysis of the current situation and management requirements of geological data, the modeling process of spatial data is elaborated. Based on the characteristics of spatial data, the logical model of geological vector data is abstracted and designed. A physical model is proposed, and problems related to the physical storage of data such as schema partitioning, security, index and hash partitioning are explored. It realizes the function of geological feature model management and service based on cloud native, provides model support for the integrated management and service of geological data, and improves the ability of feature-based geological data management and productization service.

Big data has brought new technology, new model and new impetus to the development and reform of geological survey. Data is a valuable resource for an organization, and data architecture is an important decision for data management. This paper puts forward the requirements of geological information data architecture, analyzes the definition and classification of the architecture, expounds the core of the data architecture: data model and data flow direction, proposed the design principles of geological spatial data architecture and the management process of data aggregation, storage, management and service, and proposed a three-layer and three-support data management framework based on the upload file model and core data model of geological information, which supported the development of geological spatial data management system. The unified management and centralized service of multi-specialty geological spatial data have been realized.
Map image is widely used in our work and life. In order to meet the management and access requirements of massive tiles and improve the service capability of map image, this paper analyzes the characteristics of Web Map Tile Services, analyzes the storage mode of massive tiles, studies the GeoWebCache mechanism, and proposes a tile management and service technology implementation based on PostgreSQL storage. A technology system for the management and service of massive tiles is constructed.
