1. Definition of Aerial Oblique Photographs

Aerial oblique photographs are images captured from an elevated position, typically using a camera mounted on an aircraft, drone, or other aerial platforms. Unlike vertical photographs, which are taken directly from above, oblique photographs are taken at an angle, resulting in a more dramatic and three-dimensional view of the landscape. This perspective allows for a better understanding of spatial relationships and enhances visual storytelling.

1.1 Characteristics of Aerial Oblique Photographs

• Perspective: Aerial oblique photographs provide a unique viewpoint, showcasing the depth and scale of subjects.
• Context: These photographs often include surrounding areas, offering context to the main subject.
• Visual Appeal: The angled perspective creates more visually engaging images.

2. History of Aerial Photography

The origins of aerial photography date back to the mid-19th century. The first known aerial photograph was taken in 1858 by French photographer Gaspard-Félix Tournachon, also known as Nadar, from a hot air balloon. Over the years, advancements in technology have propelled the field of aerial photography forward.

2.1 Evolution of Techniques

• Early Techniques: The use of balloons and kites for aerial photography in the 19th century.
• Military Applications: During World War I and II, aerial photography became crucial for reconnaissance and mapping.
