I work with this polygon and try to find a way to create a new polygon from the empty gap (not distinguish it) in the middle of the polygon.
I succeed to do it with a "difference" tool- but used with another layer on the polygon and then using the difference tool.
I can also digitize the shape of the hole and create a new layer- i seeking an automated way to do it and not doing in manually.
- "Clip" hole into Shapefile
- Create Polygon from holes in polygon ArcGIS
- How to fill in a ring polygon in QGIS 2.2?
Is it possible to do it with a direct tool in QGIS 2.18.1, without aid of another layer?
