【摘要】 从数据模型和程序员角度分析了数据互操作的过程,提出了一种获取机制下的地理空间数据互操作方法,并在此基础上实现了CorelDraw软件读取ESRI的Shapefile文件中的矢量地理空间数据。此方法接口简单,可以弥补OGC自身的缺陷。更多还原

【Abstract】 The initial intention of OGC is to resolve the geodata heterogeneity in networked environment,which makes its interoperability specification limited in many case.We analyze the process of data interoperability from the aspects of data model and programmer,and propose a geo-spatial data interoperability method in mechanism of acquisition.An experiment of CorelDraw software reading ESRI’s Shapefile format data is implemented with this method.更多还原
