摘要 基于面向对象GIS模型和空间数据库技术 ,在面向对象数据库Jasmine的基础上建立了基本的空间数据库系统 通过实现空间索引结构V Reactive树、空间查询等技术 ,设计和实现了一个三维GIS实验系统 该系统能够实现三维GIS的一些典型功能 ,包括细节层次可视化、多比例尺。 Based on object oriented GIS model and spatial database technology, a basic spatial database system was built on object oriented DBMS 'Jasmine' By implementing some key techniques, including spatial index (V Reactive tree), spatial query and dynamic buffer management, a 3D GIS experimental system was created, which provides many typical functions, such as LOD visualization, multi scale and spatial query
