摘要
以西藏自治区为例,利用倾斜摄影测量和三维建模技术获取了区域内高精度实景三维模型,基于数据类型对数据库进行概念设计,基于空间数据库环境下的Geodatabase模型对三维实景时空数据库进行逻辑设计,并在此基础上开发了三维实景时空数据库管理平台,提供数据管理、数据展示、三维分析和交互浏览服务等功能,实现了对三维实景数据的管理和综合展示,使信息与数据的展示更简洁、更全面。
Taking the Tibet Autonomous Region as the task area,we used oblique photogrammetry and 3D modeling technology to obtain high-precision real scene 3D models,conceptually and logically designed the database based on data type and Geodatabase model.Based on these designs,we finally developed a 3D real scene spatio-temporal database management platform.This platform can provide users with data management,data display,3D analysis and interactive browsing services,realize the management and display of 3D data,and make the display of information and data more concise and comprehensive.
