Aerial Photography

Types of Aerial Photos:

Oblique
Vertical
Mapping

Oblique

Shot from 1,000' to 14,000' above the ground
(Blimp photography and helicopters are typically lower)
Shot at a 30 to 60 degree angle from an open
window of the airplane
Zoom lenses with professionally sharp optics may be used
for the up close and personal appearance
Oblique photos are a good way to show views of sites that are visually attractive, document site changes for purposes such as construction progress or document historic events

Vertical

Shot from 1,000' to 14,000' above the ground

Shot at 90 degree angle to the ground (looking straight down) through a camera port in the bottom of the aircraft

May be shot from low altitude in sequential frames then join images to create a mosaic with high level of detail

Verticals from 35mm and medium format are useful for providing spatial relationship among features and structures on the ground such as property lines.

Verticals are also often used as exhibits in court cases for accident scenes etc…

Verticals from 35mm and medium format are not normally ortho-rectified as mapping verticals images are but do offer opportunity to scale distances where a high degree of accuracy is not required.

Verticals for mapping, also called orthophotography, are explained on page titled Mapping.
