摘要
地理信息的访问、处理和显示效率一直以来都是一个瓶颈问题，本文介绍了地理信息数据的存储管理技术，分析了制约地理信息访问效率的关键因素，提出了地理信息数据库和内存管理相结合的技术方法，为地理信息高效访问和网络地理信息服务设计了一种新的技术途径。
The efficiency of geographic information accessing,processing and displaying has been a bottleneck problem. In this paper, the geographic information data storage and management technology is introduced, the key factors that restrict the geo- graphic information accessing efficiency are analyzed, and a technical method combing the geographic information database with RAM management is put forward. The method provides a new technical approach to the high - efficiency geographic information access and the network geographic information service design.
