三维地理空间中数据库性能优化技术研究

A Research on Technological Optimization of Database Performance in Three Dimensional Geographic Space

在三维建模与动态仿真项目的开发过程中,随着项目的不断推进,地理空间数据量不断增长,数据的存取日益频繁,三维地理空间数据库凸显出数据存储响应速度过慢、地图浏览等待时间过长的问题。通过对关系数据库性能优化技术、空间数据引擎性能优化技术、ArcGIS服务器性能优化技术实现了三维地理空间数据库性能优化,有效地解决了数据库的性能问题。

With the advancement of 3D modeling development and dynamic simulation, the in- crease in the amount of data on geographical space, the more and more frequent data access, problems arise in the 3D geographic database： the slow response speed of data access, and long waiting time for map browsing. Based on the technological optimization of relational database performance, spatial data engine performance, and ArcGIS server performance, the author of this paper has optimized the database performance in three dimensional geographic space.
