Please be aware that many of the images available are very large and may take some time to download, particularly if you are accessing the Web via a modem. The quadrangle index coverage (90 kb) is an index of the quadrangles (zipped ESRI shapefile format) available for download.

Most of the new Alaska imagery data will not be available in this service due to license restrictions. The National Map program is working on acquisition of high resolution orthoimagery (HRO) for Alaska. In areas where NAIP data is not available, other imagery may be acquired through partnerships by the USGS. Department of Agriculture's Farm Service Agency (FSA). Collection of NAIP imagery is administered by the U.S. The data is 1-meter pixel resolution with 'leaf-on'. However, the majority of the imagery service source is from the National Agriculture Imagery Program (NAIP) for the conterminous United States. Blue Marble: Next Generation source is displayed at small to medium scales. In the former resolution, every pixel in an orthoimage covers a six inch square of the earth's surface, while in the latter resolution, one meter square is represented by each pixel. USGS digital orthoimage resolution may vary from 6 inches to 1 meter. Orthoimagery data are typically high resolution images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map.
