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...

大地坐标转换经纬度源码，主要是c与h文件，有参考价值-Geodetic coordinates of latitude and longitude conversion source, mainly c and h file, there is reference value

Intersect_Tins.rar. 实现不规则三角网的内插。　求取其截面等。-Intersect_Tins.rar. realization irregular triangular net interpolation. Asks to take its section and so on.

北京市公交查询系统，C#实现，源码附上，可以改为其他城市数据-Beijing Public Transport Inquiry System, C# achieved, the source code attached, could be converted to other cities data

地理信息系统－组件开发篇所有例程。书中对各章的实例都进行了编码，读者可根据编码在光盘中找到对应的实例代码。要运行这些应用程序，必须先安装MapObjects与MapX两个组件，而无须其他软件。- Geographic information system- module development all examples regulation. In the book all carried on the code to each chapter of example, the reader has been possible to act according to codes found corresponding in the compact disc the example code. Must move these application procedures, must first install MapObjects and the MapX two modules, but does not need other software.

一个不规则三角网的生成算法，比较有效，希望大家一起交流。-a TIN generation algorithms, more effective and hope that we all share.
