三维仿真地图的地理空间信息数据构建技术研究

Research on Geographical Spatial Information Data Construction Technology in 3D Simulation Map

以华南理工大学建设三维仿真地图系统的经验为依托,通过外业采集、对多源数据处理修补等方法完成了基础数据的构建准备,探索研究了三维模型可视化构建中数据生成和三维仿真地图构建的关键技术、执行标准和流程;并利用SOA架构和松耦合方式集成了多种子系统和数据库群,使得地理空间数据在组织、存储和使用方面更加科学合理,系统功能更强更稳健。

Based on the construction experience of 3D simulation map system in the South China University of Technology,we used the methods of field acquisition and multi-source data processing patching to complete the preparation of basic data construction,and explored the key technologies,implementation standards and process of data generation and 3D simulation map construction in 3D model visualization.And then,we used SOA and loosely coupled mode to integrate multiple subsystems and database groups,which could make geospatial data more scientific and rational in organization,storage and use.
