Photographs of Mexico City in 1969 and 1996 (NASA photograph AS9-19-3011 and NM22-741-54B). These two images differed greatly in scale and look angle. It was still possible to georeference the images to one another. The inset shows detail from the 1969 image that has been rotated to match the orientation of the 1996 image. A sketch map illustrating the major canals and other distinctive features visible in the images. Small arrows indicate Licenciado Benito Juarez International Airport used for scale.
