Abstract: Aiming at customized and intelligent 3D real-scene services,this study follows the concept of “one database with multiple capabilities,on-demand assembly” and systematically reconstructs and optimizes the existing technical framework to address current shortcomings in geographic entity data applications,dynamic assembly,and access control.Using Xi'an city's geospatial data as the data source,the research innovatively integrates commercial cryptographic algorithms and proposes a technical method that supports real-time online service assembly and fine-grained access control.Experimental results demonstrate that this method significantly improves the efficiency of constructing geographic entity online services,effectively reduces data preprocessing time,and exhibits notable advantages in key performance metrics such as dynamic entity assembly,multi-level access control,and intelligent on-demand delivery.This study effectively enhances the online service efficiency of geographical entity data,providing a technical reference for the management and service applications of real-scene 3D data.
