Question

Which type of aerial photography is best for showing the horizon?

• A. Low oblique
• B. High oblique
• C. Vertical
• D. Ground

Hint:

Remember: \[ \boxed{ \begin{aligned} \text{Vertical Photograph} &\rightarrow \text{No horizon} \text{Low Oblique} &\rightarrow \text{No horizon} \text{High Oblique} &\rightarrow \text{Horizon visible} \end{aligned} } \]

Answer 1

The Correct Option is B

Concept: Aerial photographs are classified according to the inclination of the camera axis.

Step 1: Differentiate the types.
• Vertical photograph $\rightarrow$ Camera axis is nearly vertical.
• Low oblique photograph $\rightarrow$ Camera is tilted, but the horizon is not visible.
• High oblique photograph $\rightarrow$ Camera is tilted sufficiently so that the horizon appears in the photograph.

Step 2: Identify the correct type. Since the horizon is visible only in a high oblique photograph, \[ \boxed{\text{High Oblique Photography}} \] is the correct answer. Therefore, the correct option is \[ \boxed{(B)\;\text{High oblique}.} \]
