Will all aerial photographic film held by USGS be digitized?
Yes, there is a plan to scan and digitize all rolls of film. The plan is to first scan all rolls of film that are in danger of decay from vinegar syndrome and then scan everything else. Science and customer requirements are also reviewed on a regular basis, but a formal, online schedule is not available.

What is a digital orthophoto quadrangle (DOQ) or orthoimage?
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. Unlike an aerial photograph, an orthoimage has a uniform scale, so it can be used as a base map...
Are the scanned aerial photographic images georectified?
Scans of traditional aerial photography film products (air photos) are not georectified . The USGS does, however, offer several orthoimagery (georectified aerial photograph) products: Digital Orthophoto Quadrangle (DOQ) High Resolution Orthoimagery (HRO) National Agriculture Imagery Program (NAIP, NAIP Plus) NAIP orthoimagery has been collected for the entire conterminous United States every 3...
How much area does an aerial photograph cover?
The area covered by an aerial photograph (air photo) depends on the scale of the imagery. Most air photos were taken on 9 x 9 inch film. The chart below reflects coverage for a variety of photographic scales. Scale 1 inch = feet 1 side (miles) Area (square miles) 1:12,000 1000 1.70 2.9 1:20,000 1667 2.84 8.1 1:24,000 2000 3.41 11.6 1:40,000 3333 5.68 32.3 1:58,000 4833 8.23 67.73 1:63,360 5280 9...

An aerial photograph looking west along the coastline of the current flow field. The Ki entry continues to produce a small plume, which is distributed along the newly formed delta. The color change in the ocean near the entry is due to the wave erosion of material from the delta and the lava itself.

Spatially explicit rangeland erosion monitoring using high-resolution digital aerial imagery
Nearly all of the ecosystem services supported by rangelands, including production of livestock forage, carbon sequestration, and provisioning of clean water, are negatively impacted by soil erosion. Accordingly, monitoring the severity, spatial extent, and rate of soil erosion is essential for long-term sustainable management. Traditional field-based methods of monitoring erosion (sediment traps,AuthorsJeffrey K. Gillan, Jason W. Karl, Nichole N. Barger, Ahmed Elaksher, Michael C. DuniwayUsing high-resolution digital aerial imagery to map land cover
The Upper Midwest Environmental Sciences Center (UMESC) has used aerial photography to map land cover/land use on federally owned and managed lands for over 20 years. Until recently, that process used 23- by 23-centimeter (9- by 9-inch) analog aerial photos to classify vegetation along the Upper Mississippi River System, on National Wildlife Refuges, and in National Parks.

The Arctic Coastal Plain of northern Alaska, an area of strategic economic importance to the United States, is home to remote Native American communities and encompasses unique habitats of global significance. Coastal erosion along the Arctic coast is chronic and widespread; recent evidence suggests that erosion rates are among the highest in the world (as high as ~16 m/yr) and may be acceleratingAuthorsAnn E. Gibbs, Bruce M. RichmondHistorical Orthoimagery of the Lake Tahoe Basin
The U.S. Geological Survey (USGS) Western Geographic Science Center has developed a series of historical digital orthoimagery (HDO) datasets covering part or all of the Lake Tahoe Basin. Three datasets are available: (A) 1940 HDOs for the southern Lake Tahoe Basin, (B) 1969 HDOs for the entire Lake Tahoe Basin, and (C) 1987 HDOs for the southern Lake Tahoe Basin. The HDOs (for 1940, 1969, and 1987AuthorsChristopher E. Soulard, Christian G. RaumannAerial Photographs and Satellite Images
Photographs and other images of the Earth taken from the air and from space show a great deal about the planet's landforms, vegetation, and resources. Aerial and satellite images, known as remotely sensed images, permit accurate mapping of land cover and make landscape features understandable on regional, continental, and even global scales. Transient phenomena, such as seasonal vegetation vigor aAuthors - News
