I am working on spliting a polygon which includes multiple points.

I tried it manually but due to the large dataset it is very time consuming.

Are there any automated tools or plugins to do that?

I wanted to split polygon which includes the point (Multiple Location).

The final output will be a polygon for each point.

    split means 'divide'. Can you elaborate in your workflow? What's your expected output?

  • split polygon which having more than one points so i will get each polygon for each point after spatial joining on the polygon shape file May 6, 2015 at 6:33

    First step could be to create Voronoi polygons djjr-courses.wikidot.com/soc128:qgis-voronoi-polygons.

  • Any other steps. i tried with Voronoi polygons but i am editing zip town borders( polygons) and Address (Points). i want polygon for each address that i will get after spatial join. Voronoi cant give me the exact zip borders. May 6, 2015 at 6:58
  • @user30184 has a good suggestion, but in your case it would (might) require being able to use a processing extent as recently asked at gis.stackexchange.com/questions/145034 (with no answer). At the same time, this might be a duplicate of gis.stackexchange.com/questions/135929 if that method/solution would work for you. Otherwise it would be helpful if you could say how you want to split them up - does it matter how big they are, is there a value or other attribute of the point that relates to size or area?
