I have received from a client 2 shapefiles, one in a polygone shape, the other one in lines.
I don't know how he managed to do what he did but my lines don't extend to the polygon limit.
Instead, I have a small line placed randomly Inside that same polygon (representing a road segment).
Here is an image so you can understand what I am talking about.
My question is : How can I extend those lines to the limit of the polygon ? In the same image, you will see that sometimes I have 2 lines within the same polygon, so if in addition to extending the lines, if I could merge the ones that come in double / triple, it would be even greater.
Any help would be very welcome. It is a rather large city and it would make my job a lot easier (and prevent any mistake) if I could do it automatically.
