基于ArcGIS 10.1的基础地理数据库升级及性能分析

摘要

As the updating speed of geographic data becomes faster,the volume of data increases rapidly,and the load of urban fundamental geographic information management system becomes larger. To increase the efficiency,it is necessary to use information soft and hardware technology synthetically to optimize the management system and its envi-ronment. This paper analyzes the change of ArcSDE between the 10. 1 and 9. 3 ArcGIS,concludes the main factors that influence the capability of the management system,and compares the change before and after update.%随着数据更新频率的加快，现势数据及历史数据迅速增加，城市基础地理数据库管理系统的负载越来越大。为了提升系统效率，需要综合利用信息软硬件技术对系统本身及其运行环境进行全面的改善与优化。本文结合项目实施，浅析了ArcGIS 10.1与9.3空间数据库变化，对影响数据库系统性能的主要因素进行了总结分析，并对升级前后的效率变化进行了对比。
