说明：  本程序是基于VB编写的，也可以在vb.net中运行。内附数据文件，详细的源代码及注释说明，可运行文件，所有的工程项目都在文件里，可查看。解决了离散点等值线的三角化问题，也可用于不规则三角网TIN计算土石方。离散点数据是GPS数据，只要按规定格式任意输入的数据都能运行。程序还包括画图功能，数据过大的话需要做缩小处理，图形绘制界面有限，但不影响输出结果。输出结果也可以保存成TXT文件方便查看对比。总的来说是个很不错的程序，需要的可以下载下来学习依下，很值得学习。由于编者的能力有限，程序不够完善或者问题的地方希望大家指正，一起学习一起进步，谢谢。
(This procedure is based on VB and can also be run in vb.net. Attached data files, detailed source code and notes, runnable files, all engineering projects are in the file, can be viewed. The problem of triangulation of isoline of discrete points is solved, and it can also be used in TIN to calculate earthwork. Discrete point data is GPS data, as long as the data input according to the prescribed format can be run. The program also includes drawing function, if the data is too large, it needs to be reduced, and the graphics drawing interface is limited, but it does not affect the output results. The output can also be saved as a TXT file for easy viewing and comparison. Generally speaking, it is a very good program, what you need can be downloaded and learned, so it is worth learning. Due to the editor's limited ability, the program is not perfect or the problem where I hope everyone to correct, learn together and progress, thank you.)
