摘要
为解决Oracle 10g SDO网络的数据上载问题,提出了SDO网络的自动建立方法.该方法在矢量图的基础上,使用SDO网络的API编程实现,从而省去了连通性信息数据的人为处理,具有一次性建立和通用性的特点.同时为实现SDO网络在多种GIS软件平台下的具体开发与应用,提出了基于MapX/MapXtreme实现其数据可视化的方法.通过MapX/MapXtreme图层加载方式可直接实现数据的可视化,并在可视化实现过程中不必考虑不可转换的Oracle对象问题.
The auto-creating method is provided for Oracle 10g SDO network in order to solve the problem of loading dada. The method is implemented by API of SDO network based on vector graphics. According to the method, it can leave out the treatment of connecting information data by hand and has one-off foundation and general character. The method of data visualization is also put forward based on MapX/MapXtreme in order to implement concrete development and application for SDO network at muhi-GIS software platforms. The data of SDO network can be visualized directly by adding or inserting layers with MapX/MapXtreme, and the instance of unsupported Oracle objects can be ignored in the process of visualization.
