I would like to look at only 50% of the area. To do this, I would like to divide the surface into two equal areas. (Afterwards, I would like to automate it using the model builder). I have followed this tutorial:
Splitting polygon into equal area polygons using QGIS
https://spatialthoughts.com/2021/06/12/split-polygons-qgis/
At the point where the application "Voronoi - Polygone" is executed I fail, because this requires at least tree points. But since I need only two surfaces, I have only two points. Does anyone have another idea? Or knows how I can work around my problem?
