不知道怎么表达,应该是说提取线上的拐点坐标,对于不规则的多边形边界很有用,比如地类界的坐标!

step1:将线转成点。必须要用ArcToolBox里的Data management tools->features->Split Line At Vertices,才可以;

step2:在属性表里面添加xy两字段,都用double型的;

step3:右击属性表的字段,选field calculater——advanced进行计算。

              VBA代码如下:Dim Output As Double
                                              Dim pPoint As IPoint
                                              Set pPoint = [Shape]
                                              Output = pPoint.X  '
区别就是.X或者.Y
