What is the name for the angle of rotation around the axis perpendicular to the flight line in aerial photography?

The angle of rotation around the axis perpendicular to the flight line in aerial photography is referred to as the Y Tilt. This tilt occurs when the camera is not perfectly aligned with the vertical axis during the capturing of images, leading to potential distortion in the resulting photographs. The Y Tilt specifically addresses rotations around the vertical axis, which is essential for maintaining geometric accuracy in aerial surveys.

Understanding Y Tilt is crucial for surveyors and professionals in aerial photography because it affects the orientation of the images and ultimately impacts the analysis of the captured data. By correcting for Y Tilt, practitioners can ensure that the images accurately represent the terrain and features being surveyed, which is vital for various applications such as mapping, urban planning, and environmental monitoring.
