摘要
shapefile数据格式在很多领域都有着广泛的应用,对其进行读写操作的研究也较深入。本文在研究shapefile数据结构的基础上,结合ArcObjects对象模型思想,利用ATL技术开发了针对shapefile数据格式进行读写操作的COM组件。研究表明:该组件能够降低对shapefile数据进行操作的难度;在进行空间数据操作的COM组件设计与实现时可以参考ArcObjects的对象模型思想来进行。
Because shapefile format has been widely used in many fields, it is necessary to study how to read/write shapefile further. Based on the shapefile＇s data structure and the design idea of ArcObjects Object Model, a COM component to read/write shapefile by COM and ATL technology was designed. This study shows that the COM component can reduce the hardness to read/write shapefile, and the design idea of ArcObjects Object Model is useful for design and implementation of COM component.
