I'm trying to merge three polylines in order create a polygon out of the surface bordered by them. On the picture attached, it's the region between the green, yellow and red (dotted) line that I would like to transform into a polyline.
I know two line segments can be joined into one line (How to merge lines with slightly different endpoints in QGIS?), but how can I join them if the second line doesn't end anywhere near the other?
I'm working with QGIS 2.14.3-Essen, on a Mac (as one can see from the picture attached).
Hope someone can help me with this.
When the "Polygonize" algorithm is executed, a polygon is created of different regions, as you can see in the photo attached.
And if I run the "Lines to Polygons" function I get this result:
