Description: The USGS NAIP Imagery Index service from The National Map consists of flight lines and image tile boundaries of National Agriculture Imagery Program (NAIP) orthoimagery available in our USGS NAIPPlus Imagery Service. The USGS relies on a partnership with the U.S. Department of Agriculture's Farm Service Agency for the acquisition of the imagery indexed in this service. This imagery index service provides information about the individual image tiles that can be downloaded through the USGS Earth Resources Observation and Science (EROS) Center’s EarthExplorer client. EarthExplorer allows free downloads of this public domain orthoimagery in GeoTIFF format for the conterminous United States.
