Aerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. [ 1] It allows geologists to analyze the distinguishing geological features and structures, plant cover, past history of the site, soil properties, and topography of the study area. [ 1][ 2] It is crucial in the early stage ...
A digital orthophoto quadrangle [1] (DOQ) is aerial photography or satellite imagery that has been corrected so that its pixels are aligned with longitude and latitude lines, and have a narrowly defined region of coverage. This is a widely used format introduced by United States Geological Survey (USGS). [1] The correction technique is called ...
United States Geological Survey marker on the summit of Maiden Peak (Washington) While much less expensive to compile and produce, the revised digital U.S. topo maps have been criticized for a lack of accuracy and detail in comparison to older generation maps based on aerial photo surveys and field checks.

When operational, the Center was a joint effort of the USGS National Mapping Division and the National Science Foundation United States Antarctic Program. The Center maintained the nation's most comprehensive collection of Antarctic aerial photography, maps, charts, satellite imagery, and technical reports.
Aerial survey is a method of collecting geomatics or other imagery by using airplanes, helicopters, UAVs, balloons or other aerial methods. Typical types of data collected include aerial photography , Lidar , remote sensing (using various visible and invisible bands of the electromagnetic spectrum , such as infrared , gamma , or ultraviolet ...
Geophotography (also geo-photography or geological photography) is a subfield of geology that involves the use of photography or other imaging techniques in the visible or near-visible (e.g. ultraviolet, infrared) spectrum to realistically record objects, features, and processes of geological significance. Ultimately geophotography is motivated ...
Austin S. Post (16 March 1922 – 12 November 2012 [2]) was a photographer, glaciologist, and mountaineer known for his aerial photography of the mountains and glaciers of North America, particularly the North Cascades of Washington and Glacier Bay, Alaska . Post worked for many years as a research scientist for the United States Geological ...
Photo interpretation at the U.S. National Photographic Interpretation Center during the Cuban Missile Crisis. Aerial photographic and satellite image interpretation, or just image interpretation when in context, is the act of examining photographic images, particularly airborne and spaceborne, to identify objects and judging their significance.
