I was speaking to Don Janelle at the Center for Spatially Integrated Social Science (CSISS
) yesterday, and we began talking about mapping non-spherical worlds. It turns out that one of his colleagues--Philip J. Stooke---at the University of Western Ontario has done a great deal of work on the topic. Stooke's website
, though most of the pages stem from 1999-2000, covers a number of related topics--particularly relevant for virtual globes enthusiasts now that software tools increasingly allow for coordinate system customization.
Stooke gives a link to a poster
(760K jpg) that offers a brief explanation of the Cartographic Options for Non-Spherical Worlds.
has maps and the numerical models of numerous asteroids and moons, as well as, a map of the nucleus of Comet Halley.
Stooke's latest book on the subject is expected soon.
