得到的结果如图所示,但是线是整体的。需要【用线分割】功能,split lines with lines 分割前的线,要素总数1 分割后的线,要素总数44 4、去除杂线 新建一个字段cd计算出长度,按长度排序进行选择杂线,再剔除 或者是人手工筛选删除 5、再次合并线 去除杂线之后骨干线也是分段的,可以看出【红】和【黄】两种颜色,说...

You will see the same symbology being applied to the polygons in the split_zoning_cbd layer. The styling and legend are complete now. We have our layers styled and legend labels created. Now let’s create a map using these styled layers along with map elements like, scale bar, north arr...
Pull Off a Strip Map Along a Line Okay, the header is deceiving. There is no strip map tool in QGIS. But if you want to use QGIS Atlas along a line, all you have to do is split it into segments. And there is a tool to do that in GRASS. ...
