I am facing a difficulty in QGIS (2.8.2): I have three layers:
- layer 1: layer with points
- layer 2: layer of level curves (contour lines)
- layer 3: layer of Voronoi polygons obtained from the points layer (layer 1).
What I need to get is, for each point (layer 1), the highest elevation contained in its respective Voronoi polygon.
How could it be done?
