Abstract: This paper combines GIStechnology with BIM refined model technology,by deeply researching surveying engineering and community management business,and uses information technology and intelligent mode to build community geospatial system based on EasyEarth platform and relational database.The system uses GIS technology's powerful data storage and analysis capabilities to manage community information in a unified manner,and obtain real-time dynamic data through multi-source sensor technology to realize three-dimensional visual management of community geospatial information.Through the system,it can directly manage multi-source and multi-type community data,greatly reduce the complexity of community geospatial information management,save human and material resources,and design real-time monitoring and early warning module to alert community emergencies and provide real-time data analysis.Used to assist decision making.Through the exploration and research of GISsystem in community geospatial information management,I hope to provide reference for GIS technology in refined and real-time community data management.
