It combines the image characteristics of a photograph with the geometric qualities of a map. Unlike an aerial photograph, an orthoimage has a uniform scale, so it can be used as a base map onto which other map information is overlaid and created. These images, known as orthophotos or orthoimages, provide a consistent scale that enables accurate representation of the District of Columbia's surface.
