shapefile - How to split non-contiguous feature in QGIS?


I have a shapefile with a feature that is non-contiguous. I want to split the areas on the left from the area on the right. However, QGIS's Split Features tool requires you to draw a line over the feature. When I draw a line between the two areas of this feature, it doesn't do anything.


How should I split this feature?


Here's a screen shot. The feature I want to split is in yellow.

Answer




You could try Multipart to Single Parts in the Vector toolset, which should split what you have there, a multipolyon, into its constituent polygons, from where you should be able to delete the polygons you need to.


You can always recombine them later if you need to.
