Aerial photo

Aerial photo is an image of the surface of the Earth that is obtained from the aircraft using air camera directed perpendicularly to the Earth's surface. The main parameter responsible for the quality of the image is spatial resolution (Ground Sample Distance) – the size of the pixel on the ground. This factor is related to the parameters of the flight camera that affect the altitude of the air mission and area that is covered by a single photo.
