摘要 空间分析系统是比较耗时的一种系统 ,而存储介质是制约系统速度的一个重要原因 ,在主存中组织数据库并将空间数据索引也建在主存中可以极大地改善系统性能。 Spatial analysis system is time-consuming and the storage media is one of the important reason that restrict the system speed. It will greatly improve the performance of the system if we store the database and the spatial index in main memory. In this paper, we introduce the storage structure of the spatial database and the organization of the spatial index of SADBS in detail.
