Answer:
Oblique aerial photographs are taken with the camera tilted at an angle, as opposed to vertical aerial photographs which are taken straight down. This angled view offers some advantages:
Provides a more natural perspective: Oblique aerial photographs more closely resemble what we see as humans, making them easier to interpret for those unfamiliar with reading vertical aerial photographs.
Shows details of vertical features: Because the camera is tilted, oblique photographs can capture details of the sides of buildings and other structures that would be hidden in a vertical photograph. This makes them useful for tasks such as inspecting building facades, monitoring construction progress, and creating 3D models of cities.
Helps with situational awareness: Oblique photographs can provide a better understanding of the layout of an area, including the relationships between different features. This can be helpful for tasks such as planning routes, identifying landmarks, and understanding traffic patterns.
