Tongass National Forest, Digital Orthophoto Quarter-Quadrangles, 2006-2008

A Digital Orthophoto is a digital representation of an image of the earth's surface-typically derived from an aerial photograph. Digital Orthophotos show ground features such as roads, buildings, and streams in their proper positions, without the distortion characteristic of unrectified aerial photos. Consequently, Digital Orthophotos combine the image characteristics of an aerial photo with the accuracy and scale associated with a map. Digital Orthophotos produced and used within the Forest Service are developed from imagery acquired through various national image acquisition programs. These sources include black and white, natural color, and color infrared images, depending on the technical characteristics of the imagery program. Digital Orthophotos formatted in quadrangle extents are known as Digital Orthophoto Quadrangles, or DOQs.
