<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">An image of my multiline can be seen in this post (<a href="https://gis.stackexchange.com/questions/384213/ogr-buildpolygonfromedges-fails-on-my-multiline">https://gis.stackexchange.com/questions/384213/ogr-buildpolygonfromedges-fails-on-my-multiline</a>).
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?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt">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?<o:p></o:p></span></p>
