- 面积量算工具，用于高斯投影下的多边形面积量算，其中包括两种数学计算方法。-the area-measurement tool is used to measure a polygon s area in gauss projection.it includes two kinds of mathematical algorithm
PtInRect
- 这是我写的一个实现点选中多边形的数值算法，算法进行了特别设计，速度很快，可以判断点在浮点型的多变形中或在多边形外，可以移植到UNIX或linux平台，因为这两个平台没有CRect的PtInRect() 和 CRgn的PtInRgn（）函数，这是一个很高效的算法-This is the one I wrote to achieve Polygon click the numerical algorithm, the algorithm specifically designed, very fas

ConstructTriangleWithInnerIsland
- 在ArcGIS环境下，在一个带岛的多边形内部构建Deloney三角网-in ArcGIS environment, in a belt of the island within the polygon Construction Deloney triangulation
mapx4demo实现了mapx的绝大部分功能
- 这个程序源码实现了mapx的绝大部分功能，非常经典！！并且我增加了一个重要功能，网上有许多人提出了这个功能，但是没有很好的解决。修改后，可以实现图层的动态移动，在创建折线时，当鼠标位于窗口边缘时，图幅自动平移，就像mapinfo一模一样的效果，并非简单的移动视图中心。当然你可以根据需要将功能扩充到在画直线、画多义线、画多边形的时候实现动态移动。具体功能与说明请下载后参阅ReadMeFirst。-the process to achieve the source of most of the fu
