给出了一种高效实现等值线的软件。其基本思想是采用VC++编写成可编程标准ActiveX控件形式，该软件内部封装入等值线实现算法和mapinfo电子图层等运行环境，具有对不同图层实现智能数据挖掘功能，能灵活生成不同格式等值线图层或数据文件。

 A software which can highefficiently generate isoline map is provided.Its basic idea is to use VC++ to compile a programmable standard ActiveX control mode.The inside of this software is encapsulated an algorithm for implementing isoline and operation environments conserving with map layers such as mapinfo.Thissoftware has function for data digging intellectually and generating differentisoline map layers or data files flexiblly.
