A digital orthoimage may be created from several photographs mosaicked to form the final image. The source imagery may be black-and-white, natural color, or color infrared with a pixel resolution of 1-meter or finer. With orthoimagery, the resolution refers to the distance on the ground represented by each pixel.
The High Resolution Orthoimagery collection was acquired through USGS contracts, partnerships with other Federal, state, tribal, or regional agencies, and direct purchases from private industry vendors. Since data came from a variety of sources, the resolution, area of coverage, file size, and projection varies by dataset. The USGS EROS Center manages and distributes this orthoimagery, which includes black-and-white, natural color, color infrared, and color near-infrared. Digital download products are available in a Georeferenced Tagged Image File Format (GeoTIFF).
