- W2347974447 abstract "According to the deployment of the spatial database in a distributed network environment,based on current geological information metadata standards,a specific geological survey information platform is established for metadata structures,including both the spatial database level and the layer of spatial index.So the spatial data are integrated,a unified spatial index database is built in the space within the framework of the index generating Hilbert space-filling curve scan matrix,to get one-dimensional mapping between Hilbert space arrangement of coding and spatial index information.A reasonable and efficient spatial index algorithm is designed for the overall planning and design.Unified operating methods are proposed for data integration,with a system architecture to improve the level of work for Geological Survey of information technology and complete data sharing and information service system.Experiments show that the system can directly access a relational database table for operation and maintenance,to avoid as much as possible the calls of the ArcGIS platform package ArcObjects correlation functions.In the realization of spatial indexing at the same time,the efficiency of spatial index is greatly enhanced.It provides a key spatial index system and a good support for data sharing for the geological survey information platform." @default.
