摘要
自GML(GeographyMarkupLanguage)发布以来,它逐渐被人们接受并正成为一种标准的空间数据交换格式。文中分析了基于GML的空间数据交换模式产生的必然性,继而指出其优点:不仅简化了空间数据交换的程序,能保证转换中的空间数据的完整性,而且是一个易于实现的交换模式,最后,提出了一个实现基于GML3(GML版本3.0)的空间数据交换模式的方法。
Since GML was published, it is gradually accepted by people and becoming a standard exchange format for spatial data. In this paper, it is firstly analysed that GML-based spatial data exchange comes into being inevitably. Subsequently the advantages is pointed out: it not only simplifies the exchange procedure of spatial data and can guarantee the integrality of spatial data during translation, but also is a mode that can be realized easily. Finally, a mothod of building GML3 (GML edition 3.0) -based spatial data exchange application is presented.
