I have a polygon shape loaded in QGIS, and I'd like to display every vertex' coordinates on the map in a label or popup next to it, how can I do that?
First extract your vertices with "Extract Vertices" from processing toolbox:
Then open label properties of this Vertex layer and add an expression like round($x,8) || ' ' || round($y,8) as label.
round($x,8) || ' ' || round($y,8)
