US Geological Survey Digital Orthoimagery

The purpose of the National Center for Earth Resources Observation & Science (EROS) Othoimagery website is to provide instant access to The National Map Orthoimagery. The Orthoimagery category is one of the framework layers for The National Map. Imagery can be used as a base layer for updating or deriving additional geographic information, such as transportation networks, hydrographic features, elevation, and land cover. The orthoimagery featured in the website includes High Resolution Orthoimagery, Landsat 7 Mosaics, and seamless Digital Orthophoto Quarter Quadrangles (DOQQ).
