主要是结合网上现有的2种鹰眼程序方案片段，在结合vc＋＋和mapx，编出来的鹰眼，供大家参考。-Combination of mainly two kinds of online Hawkeye existing procedures for the program fragment, in conjunction with vc and mapx, made by Eagle Eye, for your reference.

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 ~
