摘　　要：Shape File文件作为一种被广泛应用于存储矢量信息的文件,在实际Web GIS系统开发中会需要上传本地的Shape File文件并结合Web GIS系统进行缓冲区分析、热力图分析等,Web GIS后台如何解析ShapeFile文件是此问题的关键。详细介绍Shape File文件的底层结构,并以此为出发点,在.NET环境下以读取二进制流的方式解析Shape File文件,利用JSON数据格式,Arc GIS for Java Script库类,通过Web展示其图形以及属性信息。ShapeFile file is widely used to store vector information,ShapeFile file needs to upload local ShapeFile file and combine WebGIS system for buffer analysis and heat map analysis. The key to the problem is how to analyze ShapeFile file in WebGIS background. This article introduces the underlying structure of the ShapeFile file in detail,and uses this as a starting point to parse the ShapeFile file in the .NET environment by reading the binary stream,Using JSON data format,the ArcGIS for JavaScript library class,its graphics and attribute information are displayed on the web.
