4.3.1.1. Vertical aerial photographs

Try these first

1. 1.

   Define vertical aerial photograph.

   Hint

   Consider the orientation of the camera.

2. 2.

   What is the acceptable tilt angle for vertical aerial photographs?

   Hint

   Think about how much the camera can be tilted.

3. 3.

   What is a vertical aerial photograph?

   • An image at any angle
   • An image captured vertically downwards
   • An oblique image

   Hint

   Think about the camera's position.

4. 4.

   True or False: Vertical aerial photographs can have a tilt angle of up to 5 degrees.

   • True
   • False

   Hint

   Consider the limitations set on the tilt angle.

5. 5.

   A vertical aerial photograph is taken with a slight tilt of approximately 4º. Discuss the potential implications this could have on the accuracy of a resulting map.

   Hint

   Consider how precision in angles affects the output of measurements.

6. 6.

   Why is it critical to control the camera during the flight? Explain the consequences of failing to do so in a project.

   Hint

   Think about the influence of technology on data collection.
