Cahill-Keyes World Map by Others
A gallery of 9 different versions: published, and drafts in progress

For comparison, these images — whose originals vary from 10 inches to 132 feet — are each resized to ca. 35 cm long (14"), ca. 1:115 million, more or less, depending on your monitor's size and resolution. (I selected a setting of 960 pixels in a 965 pixel frame, so as to show the entire world span on a screen.) Until I make a slide show, you may want to open each world map in a separate tab, then click from one to the next to appreciate their variations at a glance. There are also three extra frames at the end showing detail close-ups of selected map areas.

1) [Prequel: original hand-drawn design by Gene Keyes, 1975.]

Lakes and updated borders by Duncan Webb.
This is now the basic chassis of the Cahill-Keyes World Map at any scale from 1/1,000,000, as well as larger or smaller.

6) Joe Roubal: 1º satellite composite,
a jpeg screenshot, reduced from a 1,374 MB 1/10 million tiff, 4 m (13') long:
counterpart of his award-winning Cahill-Keyes 1º globe.

(This superb incomplete draft is a close approximation of the Cahill-Keyes Octant Graticule,
but lacking its "supple zone" adjustments to prevent kinks at the octant joints.)
