Aerial Photogrammetry Quiz

What is the primary objective of aerial photogrammetry?

• To create 2D maps

• To measure the Earth's curvature

• To determine land ownership

• To produce 3D models of terrain

Which of the following is the main type of aerial photograph used in photogrammetry?

• Vertical photograph

• Oblique photograph

• Panoramic photograph

• Infrared photograph

What is the scale of an aerial photograph primarily dependent on?

• Camera focal length and flight altitude

• Sun angle and terrain type

• Weather conditions

• Latitude and longitude

Which camera parameter is crucial in aerial photogrammetry?

• Focal length

• Exposure time

• Shutter speed

• Aperture size

The principal point of an aerial photograph is:

• The exact center of the photograph

• The highest point in the terrain

• The lowest elevation in the image

• The intersection of the fiducial marks

Which factor affects the ground resolution of an aerial image?

• Flying altitude

• Camera focal length

• Sensor resolution

• All of the above

What is the purpose of a fiducial mark in aerial photogrammetry?

• To indicate the scale of the image

• To identify key locations in an image

• To align overlapping images for stereo viewing

• To define the principal point

Which of the following best describes relief displacement in aerial images?

• Objects leaning away from the center of the image

• Objects appearing shorter due to perspective

• Shadows caused by high sun angles

• Color distortion due to atmospheric effects

Which method is used to correct relief displacement in aerial images?

• Orthorectification

• Histogram equalization

• Image compression

• False-color rendering

What is the purpose of a stereopair in aerial photogrammetry?

• To increase the image resolution

• To create 3D perception of terrain

• To remove distortions

• To identify color variations
