Question:
What is meant by the scale of the aerial photograph?
Answer:
Scale refers to the relationship of distance on photographs or maps to the actual ground distance. It is a ratio that could represent any unit of measurement. For example, a scale of 1:40,000 means 1 inch on the photograph equals 40,000 inches on the ground, or 1 centimeter equals 40,000 centimeters on the ground.
