转换Mapinfo公司的tab和mif文件格式的源代码

这是两年前做的东西，刚刚开始学习gis时导师布置的一个作业：莫霍面的一些分析处理！对初学者有用，呵呵～里面有坐标系的关键转换技术，自己建的数学模型自己实现，还有配套的文章发表，呵呵～-That was two years ago so things just started learning gis instructor at the layout of a work : Moho some analysis! Useful for beginners, Ha ha ~ coordinate system with a key switch technology, to build the mathematical model for achieving his, also supporting the article was published, Ha ha ~
