Why is there no key to aerial photos

 There is no key to aerial photos

Because it explains the phenomena as they are in nature.

Aerial photographs are images taken vertically in the air using a high-resolution camera. These images are in the form of a film, mostly black and white, and it may be using colored infrared.

Types of aerial photos

Depending on the direction of the camera axis:

• Vertical images.

Low tilt images.

• High-tilt images.

• Vertical images: where the axis of the camera is in a vertical direction, which leads to comfort when looking at the image, and vertical images cover less area of ​​the region and are often used in mapping, and vertical images are difficult to take in unstable weather.

• Low-tilt images: They are the opposite of vertical images, where low-tilt images are taken by tilting the camera axis by more than three degrees, which makes the horizon not appear, and the horizon is the area where the sky meets the earth.

High-tilt images: They are in which the camera axis is tilted to a large degree, up to 60 degrees, and it covers a large area of ​​land that allows the horizon to appear, and it also gives a smell to the person taking the pictures. High-tilt images help in discovering the prominent terrain of the earth.

According to the image scale:

·       Aerial photos are large in size.

·       Small size aerial photos.

Aerial photographs are large in size: they are taken when the plane is at a low altitude, and the camera takes pictures in a small area, but the dimensions are large and show more details, as the ratio of the image distance to the ground is of a high value.

Small-sized aerial photos: They are taken when the plane is at a higher altitude than large-sized photos and cover a larger ground area and help in studying areas that are not interested in knowing the details.

The difference between aerial photos and satellite photos

• By definition.

• In terms of features.

By definition:

Aerial photos are photographs that are taken by planes or helicopters and are mainly used in mapping. The first to obtain a patent for the first process of photographing aerial photos is Tornachon in 1855, as it took three years and used an automatic camera and biplanes that were in the First World War and made By taking pictures of the enemy's trenches, and he also used them to take pictures of cities after the end of World War I. As for satellite images, they are taken by satellites that revolve around the Earth. Satellite images for mapping, weather knowledge and environmental monitoring. Governments, educational institutions and companies have benefited greatly from these images.

In terms of features:

Aerial photos are better than satellite photos in business, and their cost is lower and more accurate and clear than satellite photos. Aerial photo maps are more recent than satellite photo maps, as the available ones are more than a year old, so they do not show recent developments and it is easy to get a photographer for aerial photos. Satellite images are relevant in weather forecasting, especially dangerous hurricanes, as they cover larger areas of land than aerial images.

Disadvantages of aerial photographs

• Require experience.

• Not suitable for some seasonal conditions.

• The scale of aerial photography is not fixed.

• Not suitable for some areas.

Experience required:

In aerial photographs, only one person can be relied upon instead of a team, but he must be experienced, and the costs of equipment are very expensive, and therefore qualified persons must be employed to avoid damage to that equipment.

Not suitable for some seasonal conditions:

Taking aerial photos depends on weather conditions, as taking photos at the time of rain may cause many problems, and the photos may not be accurate. A specific timetable must be set for taking photos. Taking aerial photos is affected by several factors, namely wind speed and temperature, as the temperature Affect the sensor on the aircraft.

Aerial photography scale is not fixed:

The unstable scale of aerial photography leads to distortion in the image, so it is not possible to rely on aerial photographs to know the distance, area, and direction, and the distortion must be removed to obtain accurate information.

Not suitable for some areas:

Where there are some areas where it is prohibited to fly aircraft, especially populated areas, to protect the privacy of people residing in those areas

The importance of aerial photographs

·       In real estate.

·       In business.

·       in agriculture.

In real estate:

The real estate seller can benefit from the aerial photos of the house for sale because they show more details and information than the photos taken on the ground. They also show the exact size of the property, seeing the nearby houses, whether it is near a school or not, the backyard of the house and the swimming pool if it is in it, as well. Aerial photos show the landscape around the house, which increases the chance of selling the house.

In business:

Where the business owner can use aerial photos to display the services he provides and publish them on the Internet, which motivates customers to visit the site. Placing them on posters, banners, roadside ads, blog posts, web pages, and social media creates unique and highly engaging images and is one of the best forms of digital marketing.

in agriculture :

Aerial photos can be used to evaluate the agricultural land and the quality of the crop, which increases the productivity of the agricultural project and reduces the hours of supervision on the agricultural land.

uses of satellite images

• Preserving wildlife.

• Mitigating risks.

Preserving wildlife:

Satellite images helped in collecting many geographic data on wildlife, which led to accurate statistics on endangered species in remote areas. Wildlife is threatened by overfishing, shelter loss and deforestation. Satellite images also helped in monitoring bird migration.

Risk Mitigation:

Obtaining information in a short time helped reduce the harmful effects of disasters, emergency management and identification of potential natural disasters such as floods, earthquakes, volcanoes, fires and hurricanes around the world.
