Aerial photography is an intriguing field that professionals use for a variety of purposes. The scale of an aerial photograph is determined by the camera's characteristics and the height at which it was taken. There are two main types of aerial photography based on scale: vertical and oblique. In this article, we'll discuss the basics of aerial photography, including the types of photographs, the scale, and the equipment used.
An aerial photograph is any image taken from the air. It is usually taken vertically from an aircraft with a high-precision camera. There are several factors that differentiate one photograph from another in the same area, such as the type of film, the scale, and the overlay. Other important concepts used in aerial photography are stereoscopic coverage, fiducial marks, focal length, roll and frame numbers, and flight lines and index maps. The 52 Weeks Project is a photography challenge that encourages photographers to take 1 photograph every week for 52 weeks.
During World War I and II, aerial photography was widely used due to its military potential. Aerial photographs of the Earth are ideal for expanding regional areas and allow us to better identify and mitigate changes over time. Aerial photography is taking pictures from an elevated position, often using an airborne ship such as a rocket, airplane, hot air balloon or drone. The scale of an aerial image determines what area of land it covers and with what level of detail. Knowing the scale of an aerial photograph allows you to easily calculate distances, lengths, and areas of features. The company produces its own vertical aerial photographs, oblique photographs, point clouds and height data derived from aerial and mobile mapping programs.
Aerial photographs are snapshots over time that provide us with historical perspectives on how landscapes used to be and how they look today.
Types of Aerial Photographs
Aerial photographs can be taken in vertical, low oblique or high oblique positions. Most aerial photographs used in remote sensing are vertical photographs. Those that are tilted less than 3 degrees are still considered vertical photographs, unlike oblique photographs.Scale
The scale depends on the altitude of the aircraft and can vary in sharpness and detail. When deciding which type of aerial photography to use, it depends on its purpose.There are many aerial image providers that capture their own images or distribute them on behalf of others in their database.
