[Qgis-user] Azimuth and orientation of 2 features

[Alexandre Rodier]

Hi all.
I asked yesterday how to resolve this problem: 
"I need to calculate the orientation (North, East, South or North) of a feature (Polygon, a parcel) respect of another one (Line, a road).I calculated the azimuth of the two features using the centroids of each but the formulas I found don't really work, or I am doing something wrong (it's probably that :-) )."
Thanks to Nicolas Cadieux I found this solution:
degrees( azimuth( make_point( to_real( "Cen_X" ),to_real( "Cen_Y" ) ), make_point(to_real( "X-centr" ),to_real( "Y-centr" )) ) )

Where Cent_X, Cent_Y, X-centr and Y-centr are respectively the centroides of my road and my parcels.
Regards.
