Important Factors You Have to Acknowledge in Aerial Photography
Aerial photography consists of photos of the ground taken from high altitude. Planes, balloons, helicopters, dirigibles, poles, parachutes and kites can be used as platforms for aerial photography. The beginnings of this kind of photography go back to the 19th century in France when Gaspard Felix Tournachon took photos from his balloon. Later on, people tried to use aerial photography for security or military purposes.
The number of applications is impressive. Since digital cameras are widely available for average consume, lots of people take amateurish aerial photography. Yet, there are more scientific than hobbyist applications to such photos. Cartography depends on aerial photography. Topographic maps would be very hard to create without such photos. These applications are not new, but the novelty now consists in the processing softwares such as GIS.
Geographic information systems (GIS) are now used by all mapping agencies, and aerial photography makes it possible to align the images with the real-world coordinates so that they can be registered and deployed widely. Google Maps highly depends on aerial photography, and with this model we are not far from the operational model of Google Earth that relies on satellite images to create a simulation of 3D landscapes.
Commercial advertising, surveillance, artistic projects and environmental studies are just a few other domains in which aerial photography plays a very important role. The possibility to document events and features on private properties is one other noteworthy issue here. Anything that can be viewed from public space can be photographed without infringing the right to privacy, and aerial photography serves for such applications.
Aerial video is becoming the alternative to aerial photography, since you can use a GPS system to embed meta data in a video. Aerial photography thus gets more and more complex applications thanks to the continuous scientific developments. And the exquisite design of cameras has a heavy word to say in the matter.
As for private applications, people use aerial photography to determine the limits of land properties or to simply get nice pictures without a certain practical objective in mind. Mention must be made here that aerial photography requires the use of a very good digital camera, with a motion stabilizer and great good optics. Otherwise, the photos will be shaky, blurred and hard to use.
