Have you seen,
The historic map layer on Google Mars?
On the newest google earth, click the sky / other planets icon. Select Mars. When that loads, go to the layers menu and open the "Historic Maps" folder. There Green's map from 1877, Giovanni Schiaparelli's 1890, Lowell, and Antoniadi. There is also a USAF map fron the early sixties.
I know it is not what you were looking for, but fun none the less.
