| 摘 要： | 分析了GDC的"胖管道"语义转换模型与"语义转换"功能的构成与实现,给出了CAD数据与GIS数据实现复杂语义转换的应用示例。结果表明,基于GDC空间数据语义转换模型开发的空间数据转换软件,不仅可以满足GIS/CAD的通用数据交换需求,还可以通过在数据交换过程中增加映射文件的处理方式,满足复杂的数据交换应用。 |
| 关 键 词： | GDC 语义转换 映射文件 |

| Abstract: | Fat channel semantic conversion model, function structure and realization of GDC were analyzed in this paper. And we also provided an application example in complicated semantic conversion between GIS data and CAD data. It was proved that the spatial data conversion software based on GDC Semantic Conversion Model can not only satisfy the needs of GIS/CAD common data conversion but also met the needs of complicated data conversion applications by use of dealing with mapping file during converting. |
