Question

Write a short note on size of Aerial Photograph.

Answer 1

The size of an aerial photograph refers to the physical dimensions of the photograph captured from an aircraft or drone. A standard aerial photograph typically measures 23 cm × 23 cm (or 9 inches × 9 inches). However, other sizes may also be used depending on the camera system and the purpose of the survey.

The photograph covers a specific ground area, known as the ground coverage, which depends on factors such as the focal length of the camera lens and the flying height of the aircraft. Larger photograph sizes allow for wider ground coverage and greater detail, making them valuable for applications in mapping, land use planning, forestry, agriculture, and environmental studies.
