[3] [4] Two major axes which originate from the camera lens are included. [3] One is the vertical axis which is always at 90° to the study area. [3] Another one is the camera axis which changes with the angle of the camera. [3] To capture a vertical aerial photograph, both of these axes must be in the same position. [3]
Today, aerial survey is often recognized as a synonym for aerophotogrammetry, a part of photogrammetry where the camera is airborne. Measurements on aerial images are provided by photogrammetric technologies and methods. [1] Aerial surveys can provide information on many things not visible from the ground.
In pictometry five rigidly mounted cameras provide one vertical and four low oblique pictures that can be used together. In some digital cameras for aerial photogrammetry images from several imaging elements, sometimes with separate lenses, are geometrically corrected and combined to one image in the camera.

Close Range Photogrammetry (CRP) can mean photographs taken from the ground with a handheld camera, or taken from a UAV/drone at a relatively low altitude. PhotoModeler and CRP are used for performing measurement and modeling in agriculture, archaeology, architecture, biology, engineering, fabrication, film production, forensics, mining ...
SOCET SET inputs digital aerial photographs, taken in stereo (binocular) fashion, and from those photos it automatically generates a digital elevation model, digital feature (vector data), and orthorectified images (called orthophotos). The output data is used by customers to create digital maps, and for mission planning and targeting purposes.
Low altitude aerial photograph for use in photogrammetry. Location: Three Arch Bay, Laguna Beach, California. Photogrammetry is the science and technology of obtaining reliable information about physical objects and the environment through the process of recording, measuring and interpreting photographic images and patterns of electromagnetic radiant imagery and other phenomena.
The A3 camera consists of dual CCDs with two 300mm lenses mounted on a special motor controlled axis that is attached to the frame, a fast compression and storage unit, and a dual frequency GPS. During flight, sequences of frames are exposed in a cross-track direction at a very high speed, providing a FOV of up to 106 degrees.
