I am trying to use Voronoi polygons algorithm in QGIS in a dataset of points but strangely I am getting an overlap of polygons. These points correspond to the vertices of a set of polygons.
When using MMQGIS the polygons are correctly defined, however I can't use this plugin for the number of points I need to use (much higher number of points) and since I can't set a buffer in this algorithm.
Attached you will find some screenshots of the results I got: - Fig1 is the set of polygons from which were extracted the vertices - Fig2 are the voronoi polygons obtained from the native qgis algorithm - Fig3 are the voronoi polygons obtained from MMQGIS plugin
It is observed from the selection that there is an overlap of some polygons.
How can I avoid this?
delete duplicate geometries
tool before creating the Voronois.
