Usage

bearing(x)

## S4 method for signature 'CanopyPhoto'
bearing(x)

## S4 replacement method for signature 'CanopyPhoto,Angle'
bearing(x) <- value

Arguments

x	CanopyPhoto.
value	Angle that represents the bearing of x.

Details

Bearing is a synonym for azimuth commonly used in geotagged photographs. Like azimuth, it is the angle between the North direction and the line of sight projected to the leveled plane. Since it is used for non-hemispherical-photographs, the line of sight refers to the centerline of the cone of vision (see details of lensPolyCoef). But if the photographs have been taken looking directly to the zenith (90 degrees of elevation), bearing does not make sense. In that case, bearing refers to the orientation of the top of the frame, which means taking photographs with the top of the camera facing the bearing. The same is valid for downward looking leveled hemispherical photographs.

Value

Angle.
