In imaging, which statement best describes 'look angle'?

• A. It is the relative orientation of the aircraft to the target (e.g., north looking south)
• B. It is the weather-induced tilt
• C. It is the altitude above target
• D. It is the camera shutter speed

Answer: (A)

Look angle is the direction the imaging sensor is looking relative to the target—the line of sight from the aircraft to the target. If the aircraft is north of the target and the camera points south, that describes the look angle. This orientation shapes the imaging geometry: how oblique the view is, the perspective, shadows, and the ground footprint you end up with. The other choices describe different things: weather-related tilt, altitude above the target, or camera shutter speed, none of which define where the sensor is looking relative to the target.
