I am using QGIS 3.12 and I would like to plot an error ellipse at the tip of a vector arrow.
I have plotted GNSS velocity vectors in a map and now I would like to plot the error associated to the vector. How could I do it ?
I have tried to add an ellipse in the symbology, but not sure how to locate it at the tip of the vector arrow. The idea is to produce a similar map as the one below. The arrows indicate the displacement direction and velocity (vector length) of Iberia respect a fixed Africa from GNSS measurements and the ellipse the associated error.
The origin of the vector is the location of the GNSS station and the arrow tip location depends on the vector length. Is at that arrow tip that the ellipse would be located.
