Why does my orthoimagery search on The National Map return multiple tiles for downloading?
Orthoimagery is usually very large in file size, so we stage the data in "tiles" that can be reasonably transported over the Internet. Orthoimagery from the National Agriculture Imagery Program (NAIP) that is distributed via The National Map Data Download is in compressed 10:1, JPEG2000 format in 3.75 minute x 3.75 minute tile extents.
A larger catalog of orthoimagery can also be downloaded using EarthExplorer.

How do I download orthoimagery products and what are the available formats?
Download orthoimagery (georectified aerial photographs) using EarthExplorer , which has the full catalog of USGS orthoimagery and aerial photography. EarthExplorer : Products Overview Format varies by type of orthoimagery: Native format, Georeferenced Tagged Image File Format (GeoTIFF), or compressed 10:1 JPEG2000 A NAIP orthoimage is included as an optional layer in the PDF format of digital...
How often is orthoimagery in The National Map updated and what are the acquisition dates?
Orthoimagery (georectified aerial photography) available through The National Map Downloader and The National Map Services is from the USDA Farm Service Agency's National Agricultural Imagery Program (NAIP), which is 1-meter resolution. Generally, NAIP imagery is refreshed on a 3-year cycle with approximately one third of the continental U.S. flown each year. The month and year of imagery...
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...
What sources were used for imagery in The National Map services?
Sources for orthoimagery in The National Map services : World view to 1:2,300,000 - NASA Blue Marble Next Generation (BMNG) 1:1,150,000 to 1:289,000 - A subset of the Global Land Survey 2000 (Landsat) Scales larger than 1:289,000 - primarily the National Agriculture Imagery Program (NAIP). The data is 1-meter pixel resolution flown during "leaf-on" conditions. Collection of NAIP imagery is...
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...
