Here is my question:
- I have a polygon shapefile represent the whole country area.
- A polyline shapefile(with a bunch of line boundaries) represent the province boundaries
So, how to decompose the polygon by the polyline inside and get the shapefile file with each province independently?
I'm a new user of QGIS.
I have done the work of combine inner/outer boundaries using
MMQGIS->merge layershows like this:
But the next step Change this polylines into polygons I can't cope with
- The post about cut the shapefile using
digitizing toolsdidn't work for me
- When I use vector -> Geometry tools -> polyline to polygon, the result shows like this:
It seems that the inner boundaries had none effect.
