5. Image scale is the relative distance on images to distance on the ground.

True

False

Knowing the image scale allows for accurate measurements.

Explanation

Knowing the image scale allows for accurate measurements.

6. Scale is always constant on an aerial photograph.

True

False

Due to the many types of distortion possible when taking an aerial photograph, scale is variable across an aerial photograph.
