摘要:
GIS系统是地理信息系统（Geographical Information System，简称为GIS系统）的简称，是一种将空间位置信息与属性数据结合在一起的系统。
管理空间坐标数据的矢量图形系统，管理性质数据的数据库管理系统，以及实现矢量图形系统与数据库管理系统双向连接的连接系统，是组成基本GIS的三个系统。
近几年来, GIS技术在全球得到了迅猛发展，已经成为IT的重要组成部分。并且，用于开发GIS系统的专业开发工具得到了飞速发展。
本文具体阐述了应用Visual C++实现一个基本矢量图形系统的基本过程。从矢量图形系统的类组织，文档管理，视图组织，图形绘制，图形操作，图形选中，图形删除，文档逆操作，图形保存等各方面，实现一个用于GIS系统的基本矢量图形系统。

关键词：矢量图形 GIS Visual C++

Summary:
The system of GIS is the geography information system( the Geographical Information System, brief name for system of GIS) to call, is a kind of to belong to sex data to combine together the space position information with of system.
Manage the space sits the vector sketch system of mark the data, manage the database management system of the property data, and carry out the vector sketch system and databases to manage the system double toward copular conjunction system, is three systems that constitute the basic GIS.
In the last few years, the technique of GIS got the fast fierce development in the world, having already become the IT importance to constitute the part.And, the professional development tool that useds for the development GIS system gets to fly to develop soon.
This stationery body elaborated the applied Visual C++ carry out basic process of a basic vector sketch system.From an organization of the vector sketch system, the text file man
