深入讨论清华山维SunwayGIS和南方CASS交换文件的数据格式,并详细介绍2种文件的转换思路与转换过程,编制二者编码对照表,最后采用C#语言开发了通用的2种文件转换程序模块。实际应用结果表明该方法能够简单、高效地完成2种格式文件转换,且2种数据格式转换前后地理要素一致,拓扑关系正确,属性信息不丢失。 更多还原
【Abstract】 This paper thoroughly discussed two data formats created by SunwayGIS and South CASS,and introduced the conversion methods and conversion processes between them in detail.Then,the encoding comparative table including the structure and content was described.Finally,the all-purpose program modules were developed.The practical result indicated: the method was simple and efficient to finish conversion,which made the two data format had the same geography,the correct topology and the same attributes. 更多还原
