【摘要】 给出了一种同时读取Shapefile空间数据和属性数据的方法,即建立一个临时数据源,通过临时数据源动态的读取属性表,设计了将ARC/VIEW中Shapefile数据格式转换成用户自己的数据格式接口程序框图,并给出了利用C++读取Shapefile文件的实现方法。该方法通过S市某建设局GIS(GeographyInformationSystem)管理系统的验证,转换了1000多幅Shapefile格式的地图,转换结果准确率达98%。更多还原

【Abstract】 A shapefile stores non\|topological geometry and attribute information for the spatial features in a data set, and its inner structure is complex. The method reading geometry and attribute information of shapefile is shown. It sets up a temporary data source, and reads attribute table dynamically. The interface frame of transforming Shapefile to another data structure is designed, and the method of reading Shapefile with C++ is given. The method is testified with the GIS(Geography Information System) manage system of S city pudong construction office, its veracity reachs 98%.更多还原
