Simply so, what are the advantages of aerial photography?
The advantages of photographs with small coverages are that they provide more detail, and less distortion and displacement. It is easier to analyze a photograph with a small coverage because similar target will have less distortion from the center to the edge of the photograph, and from one photograph to the other.
What is the difference between aerial photographs and satellite images?
The methods of creating images differs between the two techniques, as does the application of such images most of the time. While both processes can produce digital images, satellite images have greater large-scale scientific applications, and aerial photography has greater small-scale commercial applications.

Aerial photography is used in cartography (particularly in photogrammetric surveys, which are often the basis for topographic maps), land-use planning, archaeology, movie production, environmental studies, power line inspection, surveillance, commercial advertising, conveyancing, and artistic projects.How is a vertical aerial photograph used to draw a map of an area?
A special kind of aerial photograph is used for the drawing of maps.
