摘　　要：将O rac le 10g拓扑数据模型数据分为可直接可视化的数据和不可直接可视化的数据,分别叙述了基于M apX/M apX trem e对两类数据实现可视化的方法,其中对前者的实现方法不适用于后者,但对后者的实现方法能适用于前者。在可视化过程中不必考虑不可转换的O rac le对象问题。本文叙述的可视化实现方法,可为其他G IS软件平台对模型数据可视化的实现提供一定的参考。The data that can be visualized directly and the data that cannot be visualized directly are classified in Oracle 10g topology data model in this paper. This paper narrates the methods of implementation for them based on MapX and MapXtremc respectively. The methods of implementation for the former is not fited for the later, but the situation is just inversed. The instance of unsupported Oracle objects can be ignored in the process of visualization. The methods of implementation that are narrated in this paper can be provided for other GIS software platform in order to visualize the model data.
