[Qgis-user] doubts about the azimuth value obtained

[Alexandre Neto]

According to documentation, the azimute function expects two point
geometries and calculates the angle in radians between the segment that
connect them and the North direction.

It's surprising to me if it accepts something that are not points. If it
does, I would assume it uses the geometries centroids, not the boundaries.

Best regards,
