We offer the mapping communities a complete coverage of the USA with the DOQ Data (Digital OrthoPhoto Quadrangle) and NAIP data. We also have international sources of data and will be selling discounted 10cm and 25cm data through www.EarthOnDrive.com soon.
If you have data which you would like to sell online, your should send us an email and we can license the data for you. Contact us at firstname.lastname@example.org and we will be glad to assist you in your procurement process.
The Aerial Photography Field Office (APFO) has a vast amount of NAIP aerial imagery of most of the United States and its territories, with dates from 1955 to the present. Our data bundle is downloaded directly from the website and includes 2010 data over 30 states, 10 states dating 2009, and the rest dating 2008. The seamless images are created from orthoimages that have been mosaicked to show a continuous photographic map of a larger area. The orthoimagery component of The National Map is a standard seamless product with a 1-meter or finer pixel resolution and a 1,500-m x 1,500-m footprint. The images are georeferenced to WGS84 datum using the geodetic coordinate syste. The National Map is continually maintained and provides the most recent high resolution orthoimagery data.
A digital orthophoto quadrangle (DOQ) is a computer-generated image of an aerial photograph in which image displacement caused by terrain relief and camera tilts has been removed. It combines the image characteristics of a photograph with the geometric qualities of a map.
The standard DOQ’s produced by the U.S. Geological Survey (USGS) are either grayscale or color-infrared (CIR) images with a 1-meter ground resolution; they cover an area measuring 3.75- minutes longitude by 3.75-minutes latitude, approximately 5 miles on each side or a quarter of a USGS 7.5 minute quad. Each DOQ has between 50 and 300 meters of overedge image beyond the latitude and longitude corner crosses embedded in the image. This overedge facilitates tonal matching and mosaicking of adjacent images. All DOQ’s are referenced to the North American Datum of 1983 (NAD83) and cast on the Universal Transverse Mercator (UTM) projection. Primary (NAD83) and secondary (NAD27) datum coordinates for the upper left pixel are included in the header to allow users to spatially reference other digital data with the DOQ.
