Aerial and its characterization
Aerial photography exposed as separate entities (in addition to the visual exploration), and the whole band and the area of the terrain; therefore divided into photographic reconnaissance shooting single shots, routing and area.
Shooting still images of individual objects is the simplest type of aerial photography in general.
The route survey is a complex view of the shooting. Routing removed band area separate photos with overlapping by about%.
Taking the square - the most difficult type of survey as a preparation for the task and to implement it. It consists of a number of parallel routes shooting lapped about 50%.
Take individual pictures can be both planned and perspective.
Shooting area - only planned.
Perspective photos give a view of the object in the form as it is to see the human eye; they serve
to the completion of the planned; extremely useful for troop and tank commander, as they give a visual representation of the terrain. Another advantage of the perspective of photography is that it can be made out of concentrated fire antiaircraft artillery (shooting from a distance of several kilometers, especially large objects), and sometimes flying into enemy positions. Prospective photographs made at an angle of 30-40 °.
Disadvantages looking images:
- a) smaller scale in comparison with planned at the same height;
- b) tall objects cover the terrain located behind them;
- c) determining the size of objects and the distances between them is difficult.
