Design and application of geological feature model based on PostgreSQL

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.
