Q1. What is the main advantage of a bird's-eye view when mapping a landscape?
- A. It shows the exact color of every surface
- B. It reveals spatial relationships and patterns that are hard to see from the ground ✓
- C. It eliminates the need for any measurements
- D. It makes objects appear larger than they really are
Why: A view from above shows how features like rivers, roads, and forests relate to one another spatially, patterns that are often hidden when you are standing on the ground.
Q2. Which of the following is a common symbol used on maps to represent a body of water?
- A. A green triangle
- B. A solid blue shape ✓
- C. A red dashed line
- D. A yellow square
Why: Blue is the standard color used on most maps to represent water features such as lakes, rivers, and oceans.

- A. Foreshortening
- B. Linear perspective ✓
- C. Chiaroscuro
- D. Impasto
Why: Linear perspective uses converging lines and a vanishing point to make objects appear smaller with distance, creating a convincing sense of depth on a flat surface.
Q2. In a bird's-eye view, what is the typical viewing angle?
- A. Looking straight ahead at eye level
- B. Looking up from below the subject
- C. Looking down steeply from above ✓
- D. Looking sideways at a 90-degree angle
Why: A bird's-eye view is taken from high above, looking steeply downward, so the subject appears as it would to a bird flying overhead.
Q3. What does the horizon line represent in a perspective drawing?
- A. The edge of the paper
- B. The viewer's eye level ✓
- C. The brightest point in the scene
- D. The outline of the main subject
Why: The horizon line sits at the viewer's eye level, and vanishing points are placed on it, which governs how the scene recedes.
Q4. When drawing a cube from a high vantage point, where does the top face typically appear relative to the bottom face?
- A. Smaller than the bottom face
- B. Identical in size to the bottom face
- C. Larger than the bottom face ✓
- D. Hidden completely from view
Why: When viewing from above, the top face is closer to the viewer, so perspective makes it appear larger than the bottom face, which is farther away.
Q5. What is the main purpose of using scale in a map drawn from an aerial view?
- A. To make the map more colorful
- B. To show the true relationship between distances on the map and real distances on the ground ✓
- C. To hide small details

- B. Vertical photos are taken with the camera pointed straight down, while oblique photos are tilted at an angle ✓
- C. Vertical photos are taken from satellites, while oblique photos are taken from aircraft
- D. Vertical photos show only water, while oblique photos show only land
Why: Vertical photos are taken with the camera aimed straight down, producing a map-like view, whereas oblique photos are tilted, showing more of the horizon and perspective.
Q4. Why is overlap between consecutive aerial photos important?
- A. It makes the photos lighter and easier to carry
- B. It allows images to be viewed in 3D through stereoscopic analysis and joined into mosaics ✓
- C. It reduces the cost of film or storage
- D. It prevents the camera from overheating
Why: Forward and side overlap ensures that common features appear in multiple photos, enabling stereoscopic depth perception and accurate mosaicking of the imagery.
Q5. Which factor most directly determines the ground resolution of an aerial photograph?
- A. The color of the aircraft
- B. The flying altitude and the camera's focal length and sensor resolution ✓
- C. The time of day the flight takes place only
- D. The number of passengers on board the aircraft
Why: Ground resolution (or ground sample distance) depends on altitude, focal length, and sensor detail, since these determine how much ground area each pixel or grain represents.
