USGS Imagery Overlay Map Service from The National Map

The USGS_EROS_Ortho_SCALE service from The National Map (TNM) contains orthorectified digital aerial photographs and satellite imagery that are commonly referred to as orthoimagery. The imagery in this service is derived from high resolution images that combine the visual attributes of an aerial photograph with the spatial accuracy and geometric characteristics of a map. The resolution is primarily 1-meter, and the source imagery is acquired through partnerships with U.S. Department of Agriculture’s Farm Service Agency and other cooperating Federal, State, and local agencies through the National Agriculture Imagery Program (NAIP). One meter resolution imagery means that each pixel in the orthoimage covers one meter on the earth’s surface. [...]
