说明：  这就是陈建春的《用Visual C++开发GIS系统》的配套代码。 用来给初学者熟悉VC++图形编程很不错，我当初学MFC的时候就是照着这本书上手的。但作为一个GIS系统来说缺少一些必要的 要素，比如大数据量的管理、空间索引、符号化、投影等等等等等。以现在的眼光看来整个系统的架构设计也不是太好。 这本书再版后改名为《矢量图形系统开发与编程》，内容变化不大("using Visual C development of GIS systems" supporting code. For beginners to the VC familiar with graphical programming quite well, and I had the time to learn MFC is shining on this book in the business. But as a GIS systems lack the necessary elements, such as the large amount of data management, spatial indexing, symbols, such as projectors, etc.. Now the point of view of the entire system architecture design is not too good. This book reprinted later renamed as "vector graphics systems development and programming", little change)

最近几年，社会上地理信息系统和电子地图技术越来越受到大家的关注，很多单位和个人都投入了大量的人力和物力进行了相关的设计开发。在这些实际的开发问题中，我想就公交车换乘自动查询系统的核心算法的设计和分析做一个不成体统的研究，还希望同志们能帮我指正错误，帮助提高。(In recent years, the community of GIS and digital map technology is receiving increasing attention to the U.S., many units and individuals have invested considerable human and material resources to carry out the relevant design and development. In the development of these practical issues, I would like to change bus system automatically query the core of algorithm design and analysis不成体统to do a study, and also hope to help my comrades error correction to help improve.)
