Orthophotomap of Rockport, Texas

An orthophotomap or orthophotomosaic is a map made by merging orthophotos — aerial or satellite photographs which have been transformed to correct for perspective so that they appear to have been taken from vertically above at an infinite distance.[1] Google Earth maps are of this type.
