Does Google Maps use aerial photography?
More about image types & their collection dates The satellite and aerial images in Google Earth are taken by cameras on satellites and aircraft, which collect each image at a specific date and time. These images are displayed as one seamless image and the date may change as you move your cursor around the map.
What are maps created by taking aerial photographs called?
A digital orthophoto quadrangle (DOQ)–or any orthoimage–is a computer-generated image of an aerial photograph in which displacements (distortions) caused by terrain relief and camera tilts have been removed. It combines the image characteristics of a photograph with the geometric qualities of a map.
Should an aerial photograph be considered as a map?
An aerial photograph is any photograph taken from an airborne vehicle (aircraft, drones, balloons, satellites, and so forth). The aerial photograph has many uses in military operations; however, for the purpose of this manual, it will be considered primarily as a map supplement or map substitute.

How aerial photographs are taken?
Normally, air photos are taken vertically from an aircraft using a highly-accurate camera. Other important concepts used in aerial photography are stereoscopic coverage, fiducial marks, focal length, roll and frame numbers, and flight lines and index maps.
When was the first aerial photograph taken?
The first aerial image taken in the United States dates only two years later, taken by photographer James Wallace Black. On October 13, 1860, Black and his balloon navigator, Samuel Archer King, made eight exposures from The Queen of the Air, a balloon tethered above Boston, Massachusetts.
