How did aerial photography help the war?
The use of aerial photography rapidly matured during the war, as reconnaissance aircraft were equipped with cameras to record enemy movements and defenses. At the start of the conflict, the usefulness of aerial photography was not fully appreciated, with reconnaissance being accomplished with map sketching from the air.
What is vertical aerial photography?
Vertical aerial photography is used in cartography (particularly in photogrammetric surveys, which are often the basis for topographic maps ), land-use planning, aerial archaeology. Oblique aerial photography is used for movie production, environmental studies, power line inspection, surveillance, construction progress, commercial advertising, conveyancing, and artistic projects. An example of how aerial photography is used in the field of archaeology is the mapping project done at the site Angkor Borei in Cambodia from 1995–1996. Using aerial photography, archaeologists were able to identify archaeological features, including 112 water features (reservoirs, artificially constructed pools and natural ponds) within the walled site of Angkor Borei. In the United States, aerial photographs are used in many Phase I Environmental Site Assessments for property analysis.
How many feet did the Fairchild aerial survey cover?

What was the purpose of the aerial photography in 1918?
1 Squadron AFC to photograph a 624 square miles (1,620 km 2) area in Palestine as an aid to correcting and improving maps of the Turkish front. This was a pioneering use of aerial photography as an aid for cartography.
How to make a panorama?
Panoramas can be made by stitching several photographs taken in different angles from one spot (e.g. with a hand held camera) or from different spots at the same angle ( e.g. from a plane). Stereo photography techniques allow for the creation of 3D-images from several photographs of the same area taken from different spots.
When did Germany start using aerial cameras?
Germany adopted the first aerial camera, a Görz, in 1913. The French began the war with several squadrons of Blériot observation aircraft equipped with cameras for reconnaissance. The French Army developed procedures for getting prints into the hands of field commanders in record time.
Why are aerial photographs important?
Aerial photographs are vital to any study of local environmental conditions and they are used in many different ways, depending on the type of photograph used, the angle the photographs are taken at, and the elevation of the vehicle used to take them.
What is aerial photography?
Aerial photography is - as it sounds - the process of taking photographs from the air, but there is more to it than simply using a light aircraft or helicopter and flying up to take photographs.
Why do archaeologists use oblique images?
The oblique image is primarily used in archaeology to take a wider context of a feature and the area around it, and also to give depth. Nearly always taken at a much lower elevation than the vertical image and in few numbers, its application is fairly limited and often taken for a specific purpose (8).
Why is winter the best time to take aerial photos?
There are many reasons for this, not least of all that it is easier to see features in fields that do not have crops and will not be ploughed for several more months.
Which is easier to interpret: vertical aerial or oblique?
As a rule, vertical aerial photographs are easier to interpret than oblique photographs because of the standardised ways in which they are taken - with set scales and at a single non-arbitrary angle (10).
When was the first aerial photograph taken?
The first aerial photograph was oblique and taken of a French village in the late 19 th century. The man who took it - photographer Gaspar Felix Tournachon - patented the concept of using aerial photographs to compile maps (5); it was to prove much more effective than the time-consuming ground surveys that had then been the more commonly-used method of the national mapping organisations that developed throughout the 19 th century (such as the UK's Ordnance Survey). George R. Lawrence took aerial photographs of San Francisco in 1906 following the devastating earthquake, but it was not until World War I - when potentially military applications were foreseen - that a systematic process of taking aerial photographs would become key to the development of the method.
What was the Cold War and the development of colour photography?
The Cold War and the development of colour photography meant that military applications continued and it was during this period that wider environmental applications developed too. Infra-red photography became crucial to vegetation mapping (20) and also to tracking and identifying diseased plants and trees (18).
Why do photographers use aerial photographs?
In wartime, photographers use aerial photographs to locate targets. And, given advances in drone technology, the applications for this niche are growing.
What is considered an aerial photograph?
To be considered an aerial photograph, you have to take the image with equipment that is not based on the ground. And, it is not the same as air-to-air photography where photographers are capturing images of other planes or airborne craft.
How many degrees do you tilt the camera axis in a vertical aerial photograph?
Vertical aerial photographs have no tilt in the camera axis. Low oblique photographs –unlike with vertical photographs, to take low oblique photographs you tilt the camera axis more than 3 degrees in a manner that the horizon–the area where the earth and sky meet–is not visible in the image.
How many lenses are needed for aerial photography?
Aerial photography normally involves a minimum of two camera lenses attached together, which is known as a 2-lens system, but you can also use more lenses. For example, you can use a 3-lens systems to capture areas from horizon to horizon. As an example, photographers used this type of system, also called a trimetrogen system, in World War II to map enemy territory.
What type of film is used for aerial photography?
Film and Filter Aerial Photography 1 Panchromatic Images–this refers to the type of film used, which captures all visible wavelengths of energy. The image is in grayscale, and often used for reconnaissance or map study. 2 Color Photographs–color film can capture various visible bands separately. This type of aerial photography can be used to interpret objects within a study area. 3 Infrared Imagery–this refers to the use of infrared film, which records only infrared energy. This type of photography is used to study vegetation and bodies of water, for example. 4 Color-Infrared Imagery–this combines color and infrared film for vegetation studies, water body mapping, and a variety of urban applications. 5 Thermal infrared imagery–this captures not only infrared images, but temperature variations as well. Experts use this type of imagery for temperature studies.
What is the difference between aerial and terrestrial photogrammetry?
Photogrammetry combines photography and geography. The difference relates to how you take aerial photographs. With aerial photogrammetry, you take the images from an airborne craft whereas with terrestrial photogrammetry, you take the photos from a camera at a fixed, elevated terrestrial position.
