Hi,

An image of my multiline can be seen in this post 
(https://gis.stackexchange.com/questions/384213/ogr-buildpolygonfromedges-fails-on-my-multiline).
 I am trying to extract the largest polygon contained by the lines. As you can 
see in the figure, one of the linestrings has only 2 points. One of the 
linestrings has 3 points. The remaining linestrings have many points. What is 
the suggested workflow to solve this problem?

Both Polygonize and BuildPolygonFromEdges fail, even if I segmentize my 
multiline.  Must I first trim all linestrings to their intersectional segments? 
Or break them into all the pieces from all intersections?

Thanks,
Brendan
