Creating polygon from hole in QGIS?
I work with this polygon and try to find a way to create a new polygon from the empty gap 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.
I read
- "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?
polygon qgis-2.18 create holes

I recommend Digitizing Tools plugin.
Once installed, you will find a new toolbar. The eighth from the left of this toolbar, there is an icon called Fill ring with a new feature (interactive).
For you to fill all rings at once;
- Switch to Fill all rings in selected polygons with new feature mode by clicking on a small triangle (right-hand-side).
- Start editing mode and select polygons you want to work on (you can select all polygons).
- Click on the tool icon.
- A small dialog box will appear and asks you to give a new attribute value. This value will be given all fillings, so that it helps you to identify these new features in the attribute table. Hit
[OK]to close.

You can use the trace tool (on the Snapping Toolbar) and simply trace around the hole in the polygon while creating a new feature in a new layer (or your existing layer).
