WebJan 1, 2016 · 22 Define the bearing angle θ from a point A ( a 1, a 2) to a point B ( b 1, b 2) as the angle measured in the clockwise direction from the north line with A as the origin to the line segment A B. Then, ( b 1, b 2) = ( a 1 + r sin θ, a 2 + r cos θ), where r is the length of the line segment A B. It follows that θ satisfies the equation WebFor bearing: degrees (azimuth (point_n ($geometry,1),point_n ($geometry,2))) For distance: $length But you'll still have line segments.
