I'm trying to calculate a center line of an odd shaped polygon. When I've used the Polygon Tool 'Centerlines' with the setting 'All' is doesn't create center lines for all of the polygon, only part of it. This doesn't seem like it should be a terribly difficult thing to do. Are there any other ways.
The picture is of a radius of 15km from a reintroduction site at the centre. The mustard polygon (network of rivers/water) and the green line is the center line given by the 'Centerlines' tool. This green line should be within all of the mustard coloured polygon.
I've also tried the 'Centerline in Polygon Gaps' and 'Skeleton/Medial Axis' tool in the HCMGIS plugin which freezes before they can produce an output.
