基于GDI+的GML可视化模型设计

Design of GDI+ based visual model for GML

本文介绍了基于GML地理数据的可视化模型设计方法。利用文档对象模型(DOM)对GML进行解析,以及通过对GD I+自身特性的分析,展示了在.NET环境下采用GD I+类库进行可视化模型设计的优良特性,为实现GML数据可视化提供了一个切实可行的方案。

A design approach of visual model based on GML geo - data is proposed in this paper. Document Object Model （DOM） is adopted to decompose GML data. By analysis of GDI ＋ ＇s features, the excellent characteristics of using GDI ＋ class library for the visual model design under . NET framework are shown. This method proves to be a practical way in visualizing the GML data.
