The Georgian terrace of Royal Crescent (Bath, England) from a hot air balloon

Aerial photography is the taking of photographs of the ground from an elevated position. Georgian architecture is the name given in most English -speaking countries to the set of Architectural styles current between 1720 and 1840 The Royal Crescent is a notable residential road of 30 houses laid out in a crescent, in the city of Bath, England. Bath is a city in Somerset in the south west of England It is situated west of London and south-east of Bristol. England is a Country which is part of the United Kingdom. Its inhabitants account for more than 83% of the total UK population whilst its mainland The hot air balloon is the oldest successful human-carrying Flight technology A photograph (often shortened to photo) is an Image created by Light falling on a light-sensitive surface usually Photographic film or an electronic The term usually refers to images in which the camera is not supported by a ground-based structure. Cameras may be hand held or mounted, and photographs may be taken by a photographer, triggered remotely or triggered automatically. Platforms for aerial photography include fixed-wing aircraft, helicopters, balloons, blimps and dirigibles, rockets, kites, poles and parachutes.

History

Aerial photography was first practiced by the French photographer and balloonist Nadar in 1858 over Paris, France. Year 1858 ( MDCCCLVIII) was a Common year starting on Friday (link will display the full calendar of the Gregorian Calendar (or a Common Paris (ˈpærɨs in English; in French) is the Capital of France and the country's largest city ^[1]The use of aerial photography for military purposes was expanded during World War I by aviators such as Fred Zinn. World War I (abbreviated WWI; also known as the First World War, the Great War, and the War to End All Friedrich Wilhelm "Fred" Zinn was a volunteer American Aviator who flew with French Armée de l'Air forces in World War I and an early pioneer

Uses of imagery

Reflection of a hot air balloon, partially obscured by a jetty, an example of low altitude aerial photography

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, surveillance, commercial advertising, conveyancing, and artistic projects. The hot air balloon is the oldest successful human-carrying Flight technology Photogrammetry is the first Remote sensing technology ever developed in which geometric properties about objects are determined from photographic images Surveying is the technique and science of accurately determining the terrestrial or three-dimensional space Position of points and the distances and angles between A topographic map is a type of Map characterized by large-scale detail and quantitative representation of relief, usually using Contour lines in modern Aerial archaeology is the study of archaeological remains by examining them from altitude Filmmaking is the process of making a Film, from an initial story idea or commission through scriptwriting shooting editing and finally distribution to an audience See also Nature The natural environment, commonly referred to simply as the environment, is a terminology that is comprised of all living and Surveillance is the monitoring of Behavior. Systems surveillance is the process of monitoring the behavior of people objects or processes within systems for conformity Advertising is a form of Communication that typically attempts to persuade potential Customers to Purchase or to consume more of a particular Brand In law conveyancing is the transfer of title of Property from one person to another or the granting of an Encumbrance such as a Mortgage or In the United States, aerial photographs are used in many Phase I Environmental Site Assessments for property analysis. A Phase I Environmental Site Assessment is a report prepared for a real estate holding which identifies potential or existing environmental contamination liabilities. Aerial photos are often processed by a GIS system.

Advances in radio controlled models has made it possible for model aircraft to conduct low-altitude aerial photography. A radio-controlled model (or RC model is a model that is steerable with the use of Radio control. Model aircraft are flying or non-flying models of existing or imaginary Aircraft, often scaled down versions of full size planes using materials such as balsa This has benefited real-estate advertising, where commercial and residential properties are the photographic subject. Real estate is a legal term (in some jurisdictions notably in the USA, United Kingdom Full-size, manned aircraft are prohibited from low flyovers of populated locations. Small scale model aircraft offer increased photographic access to these previously restricted areas. Miniature vehicles do not replace full size aircraft, as full size aircraft are capable of longer flight times, higher altitudes, and greater equipment payloads.

Because anything capable of being viewed from a public space is considered outside the realm of privacy in the United States^[2], aerial photography may legally document features and occurrences on private property. Privacy is the ability of an individual or group to seclude themselves or information about themselves and thereby reveal themselves selectively The United States of America —commonly referred to as the

Challenges

Aerial photography includes challenges not present in non-aerial photography. Some of these include:

• Perspective correction – Aerial photographs are often taken at an angle to the object being photographed. This means that the perspective of the photograph will be incorrect with near objects larger than far away objects. Perspective correction distorts the image so that equal sized objects in the real world have equal size in the photograph. See orthophoto. An orthophoto or orthophotograph is an aerial photograph that has been geometrically corrected ("orthorectified" such that the scale of the photograph
• Registration – Aerial photographs usually are mapped to the real world objects (streets, buildings, etc) being photographed. For example, an aerial photograph may be converted into a series of lines based on the roads contained in the photograph.
• Stitching – To create an aerial photograph of a large area, multiple photographs must be taken. Image stitching or photo stitching is the process of combining multiple Photographic Images with overlapping fields of view to produce a segmented Panorama Stitching is joining those photographs together so that they form a single large photograph. This process creates "seamless" imagery.
