Aerial photography is a significant information source for landscape researchers. It includes studies like landscape archeology and environmental science. Everyone knows how to view aerial photographs, but more so if you’re a student of archeology and geography.
Students typically research large amounts of aerial photographs at the master level and are generally required to produce analytical papers and projects that use them in descriptions that go further than simply analyzing a photographic material.
In the last study, despite the abundance of electronic tools and satellite visuals for today’s charts, cartographers still need to make modern maps, mainly for calculation when compiling these maps. Aerial photography is essential to the study of general environmental conditions and is used for various purposes. Its use will depend on the kind of photograph taken, the angle of the photo, and the vehicle’s elevation when taking the photo.
How Does Aerial Photography Work?
The method of taking photos from above the air is what aerial photography is all about. But the discipline may need more than just a helicopter or light aircraft to take photos. Some issues need to be discussed in aerial surveys to make sure that all data obtained are reliable to analyze whatever is investigated. Landscape features are often difficult to view. Information can be easily missed. What might appear as a small ground bump may become significant when taken in a bigger context.
They’ve been used to study landscapes for more than a century, especially in archeology. Researchers’ knowledge about the things around us is widespread and combined with the GIS technology, with the potential that it won’t become obsolete at all soon.
Types of Aerial Photography
There are two main types of aerial photography, and they are used differently. These are vertical aerial photography and oblique aerial photography. Even at a time when digital photography is of top quality, monochrome photograms remain a preference not only because it is cheaper, it is also because the contrasts between blacks, whites, and grays make selecting characteristics easier.
- Oblique Aerial Photography
These images can usually be taken at 45 degrees. The oblique picture is generally used for archeology to present a broader context of the area and to provide scope. They are taken at lower heights than vertical photographs.
It is quite limited and is often used in a few numbers for a particular purpose. Nearer objects appear to be larger than the ones further away. Such photos have been taken from helicopters or small planes. They are suitable to monitor the degradation of land features and marks for many decades.
- Vertical Aerial Photography
This is the most common kind of aerial photograph, and it is taken directly across a landscape. It is an insight into the plan that does not distort the image. It means that the layers of land, particularly height adjustments, are hard to read, but work takes place to produce a 3D image using a tool to analyze two of them at once.
However, aerial photography doesn’t have to be such a technical method. To know more about it, simply make a search about aerial photography near me so that you’ll be led to an expert in your area in no time.
