USGS High Resolution Orthoimagery
High resolution orthorectified images combine the image characteristics of an aerial photograph with the geometric qualities of a map. An orthoimage is a uniform-scale image where corrections have been made for feature displacement such as building tilt and for scale variations caused by terrain relief, sensor geometry, and camera tilt. A mathematical equation based on ground control points, sensor calibration information, and a digital elevation model is applied to each pixel to rectify the image to obtain the geometric qualities of a map.
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.

Two digital download products are available for High Resolution Orthoimagery in a Georeferenced Tagged Image File Format (GeoTIFF). Typically, all data available from USGS/EROS are downloadable at no cost to the user. there are some cases when a service fee is required to convert the analog film record to a digital file. This non-refundable fee is $30 per scene/frame.",
