基于ArcObject二次开发的矢量数据裁剪实现

摘要

对于数据入库更新过程中需要进行矢量数据的裁剪等情况，文章分析了矢量数据裁剪过程中遇到的问题，并提出解决方法。详细说明了裁剪过程中会利用到的ArcObject中各个接口和方法，并予以二次开发实现，在实际数据操作中得以应用。%According to the requirement of the erasing of vector data uring the data update of database, this paper have analyzed the problems of the procedure of the erasing and put solutions forward. It details the use of interfaces and methods from ArcObject and the implement of the erasing by secondary developing in the procedure. The erasing function can deal with the physical data in practice in the end.
