Shapefile图形文件的数据存储格式及读写

The Interpretation of Shapefile Format and Read-writing the Data

Shapefile图形文件是ESRI(Environmental Systems Research Institute)公司提供的一种矢量数据格式.该图形文件只需要较少的硬盘空间,且容易进行读写处理,在绘制速度和可编辑功能上也优于其它的数据格式.本文详细阐述了Shapefile的文件结构,并在此基础上以Microsoft visual C++为开发平台,编写出可以读写Shapefile,并能对其进行简单操作的GIS系统.

The Shapefile is a vector data which is the ESRI（Environmental Systems Research Institute） provided.The graphics files require less hard disk space,easy to read and write.Processing in the rendering speed and editing features are also superior to other data formats.This paper describes the structure of this file,on this basis,with Microsoft visual C ＋ ＋ as a development platform,the preparation that can read and write Shapefile,and can perform simple operations as a GIS system.
