You can find numerous types of photography but none of them can be compared with Aerial Photography in terms of technical perspective. It has been used not just for art exhibit but also for gathering technical data, facts and investigation.
Aerial photography has been used for human geography - a scientific study that reveals how previous people work compared to the modern ones. It also has become very useful in terms of landscape archeology and global warming. This is the reason this kind of taking photos is always associated with science, specifically in local ecological issues.

There are two kinds of Aerial photography style that are usually being used are the Vertical and the Oblique.
Vertical style for aerial photography is in fact taking shots over a landscape directly looking all the way down. It is the most popular style being used by aerial photographers especially if only the overview of the landscape is required of them.
Vertical style much simpler to understand as compared to oblique style. Even though this style is not popular to archeological research they usually used it to check and spot things that are often missed during excavation or exploration. It can also help you analyze fascinating earthworks that you'd not notice if you're on to the ground.
Oblique style is catching images in a typical 45 degrees angle or any angle that could give the best viewpoint of the image. This kind of style is the one popular in archeology because of its wider context and its depth. It is usually used in fixed-wing aircraft like helicopter since it has the capacity to fly on a reduced elevation, which is proper to the oblique style. This style is perfectly suited in studying environmental conditions like erosion etc.
