Vertical aerial photography is a type of aerial photography in which shots are taken directly above the subject of the image. This method of aerial photography is also often referred to as “aerial aerial photography”. In contrast, oblique photographs (also known as oblique aerial photographs or oblique aerial photographs) are taken from an elevated point, forming an angle that is neither horizontal (photograph at ground level) nor perpendicular (vertical aerial photograph) to the area being photographed. When it comes to the advantages of vertical aerial images, there are many.
To begin with, they come in a variety of formats, sizes and scales, making them suitable for a wide range of applications, from precision mapping to reconnaissance photography. Additionally, vertical photographs have an approximately uniform scale throughout the photo, making them easier to interpret than oblique ones. This uniform scale also makes vertical photographs easier to use photogrammetrically, as a minimum of mathematical correction is required. Furthermore, tall objects such as buildings can be easily identified in vertical photographs.
On the other hand, one of the main drawbacks of vertical aerial images is that they are often not very recent. This means that they may not accurately reflect any changes that have occurred since the photograph was taken. Additionally, terrain features can be difficult to identify or interpret without symbols and are often hidden by other details of the terrain, such as buildings in wooded areas. Furthermore, due to the lack of contrasting colors and tones, it is difficult to use a photograph in low light.
Overall, vertical aerial photography has both advantages and disadvantages. Its main advantage is that it comes in a variety of formats, sizes and scales, allowing for a wide range of applications. However, its main disadvantage is that it is often not very recent and may not accurately reflect any changes that have occurred since the photograph was taken. Despite this, vertical aerial photography can still be a useful tool for mapping and reconnaissance purposes.
