FME数据处理03：合并相接的线要素

1 问题描述

给定如下数据集：

上图中，选中的三条线段满足相接关系，但是是断开的；我们想将它们在断点处合并起来。

2 FME流程

主要是读取shp文件，调用LineCombiner转换器，将各线段从线段的相接点处连接起来。

Takes lines and connects them to form longer lines. Each connecting line must meet at the exact same start/end point, but otherwise they must not intersect.

Any nodes with only two lines connecting to them (sometimes called pseudonodes) are removed.
