Geodatabase网络模型的研究与应用

Research and Application on Network Model of Geodatabase

为了合理地管理、存储和显示海量的空间数据,ESRI公司推出了第三代地理数据模型-Geodatabase模型,该模型是一种面向对象的数据库技术。该文详细地介绍了作为Geodatabase基本模型的网络模型的概念、特点和分类,并以路网中的最短路径和供水管网中的爆管分析为例,深入地分析了Geodatabase网络模型在实际中的应用。

In order to manage,store and show immense amount of data reasonably,ESRI Company introduced the third generation model of geographical data-Geodatabase.It is an object-oriented database system.This paper introduces conception,characteristics and classification of network model used as a basic model of Geodatabase in detail.And taking the shortest path in the road net as well as the analysis of pipe burst in the water supply network as the example,the research analyzes the network model of Geodatabase in the applications deeply.
