However, the 10-meter Alaska orthoimagery data will not be available for direct download from the National Map due to license restrictions. The National Map download client allows free downloads of public domain, 1-meter resolution orthoimagery in JPEG 2000 (jp2) format for the conterminous United States. For Alaska, 10-meter resolution SPOT imagery is provided for viewing. 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 collected with "leaf-on" conditions. Blue Marble: Next Generation and Landsat imagery data sources are displayed at small to medium scales, however, the majority of the imagery service source is from the National Agriculture Imagery Program (NAIP) for the conterminous United States. Orthoimagery data are typically high resolution aerial images that combine the visual attributes of an aerial photograph with the spatial accuracy and reliability of a planimetric map.
