Service Description: A Digital Orthophoto Quadrangle (DOQ) is a computer-generated image of an aerial photograph in which the image displacement caused by terrain relief and camera tilt has been removed. Unlike an aerial photograph, an orthoimage has a uniform scale, so it can be used as a base map onto which other map information is overlaid. It is possible to measure directly on an orthoimage, just like other maps. The USGS produces two types of DOQs: 7.5-minute (full-quad) DOQs that cover an area measuring 7.5-minutes longitude by 7.5-minutes latitude and a 3.75-minute (quarter-quad) DOQs that cover an area measuring 3.75-minutes longitude by 3.75-minutes latitude. The DOQ combines the image characteristics of the original photograph with the georeferenced qualities of a map. The DOQQ mosaics produced by IDWR are black and white (B/W) images with 1-meter ground resolution. A DOQ can be incorporated into any geographic information system (GIS) that can manipulate raster images. It can function as a cartographic base for displaying, generating, and modifying associated digital planimetric data.
