Question
Distinguish between air photos and satellite images. Explain the main conceptual terms relevant to each.
Solution
Air Photos : Aerial photography means sensing the images of the earth’s surface through cameras fitted in an aeroplane. According to the position of the axis of camera, the air photos may be grouped as vertical, horizontal, oblique, convergent and trimetrogen.
Satellite Images : Satellite imagery contrary uses a different mechanism of generating ground images. A ground sense imaged by a sensor board. The features on the earth’s surface are captured in these imageries by detecting characteristics electromagnetic radiation that is reflectance any object of different wavelengths follows a pattern which is characteristics of that object.
