11-02-05, 09:41 AM None that I'm aware of. Something that could make that difficult though is, as far as I know, they've said not all the world itself is include and there is more out there. Just doing the math itself if Eberron is the size of Earth then it's missing about 5 thousand miles at the equator. So if it's true, any globe would be incomplete and or the wrong size.

11-02-05, 09:45 AM Not to be difficult, but have we even established that Eberron IS a globe?

If so, then I'm curious about what sort of map projection is used on the map that we have. It could have a serious impact on the size of territories in the norther parts of the map.

Yeah, I'm a geography geek. What can I say?

11-02-05, 10:46 AM It's either a Gall's Stereographic Cylindrical Projection or a Mercator Projection (my bet is on the latter).

Gall's stereographic cylindrical projection results from projecting the earth's surface from the equator onto a secant cylinder intersected by the globe at 45 degrees north and 45 degrees south. This projection moderately distorts distance, shape, direction, and area.

The Mercator projection has straight meridians and parallels that intersect at right angles. Scale is true at the equator or at two standard parallels equidistant from the equator. The projection is often used for marine navigation because all straight lines on the map are lines of constant azimuth.

Both these projections allow a constant horizontal scale as seen in all our maps.

11-02-05, 12:08 PM Clearly, Eberron is actually a round disk contained within a sphere, floating within the astral plane. The sun and moons are actually manifestations of the planar boundaries coming in contact with the prime material. The few ships that have sailed far off of mapped space never seem to return, and some suspect they were pulled past some sort of planar horizon at the edge of the world, doomed to fall forever through the astral emptiness.

My bet is on the Mercator also, which leads me to think that areas like the Mror Holds and Demon Wastes are not nearly as large as they look.

11-02-05, 02:15 PM Looks like a mercator, but my bet is that the map was designed by an artist, not a geographer, and I would be suprised if they had heard of map projections. So, I'm not going to worry too much about it. ;)

11-02-05, 05:48 PM Assuming that it is a Mercator how difficult would it be to make an electronic globe of Eberron?

11-02-05, 06:56 PM First, go and get Google Earth (http://earth.google.com).

From there, it's trivial.

Download the world map at:

http://pages.videotron.com/sebby777/home.html

then use it as an image overlay in Google Earth (Add | Image Overlay), with the top of the map set at north 70° and the bottom of the map set to south 70°, with the east and west edges of the map brought around to meet.

It produces a fairly passable Eberron globe.

Note that the artists did not in fact pay any attention to projection when they drew the map! They just wanted something that looked good and gave an impression of what's in each area.

11-02-05, 07:46 PM Siran had a great idea...

Here's what you get, which also shows a relative size comparison between Khorvaire and Xen'drik.

11-02-05, 10:06 PM The irony I find with this is that Riedra is directly where Tokyo would be.

11-02-05, 10:15 PM The part I find interesting is that Zilargo must be even more tropical than I thought.

Breland must be an absolute stinker to live in.

11-03-05, 12:05 AM Thanks Siran! That should satisfy us for a little bit. Although if they did make an Eberron globe I'm pretty sure I'd buy it. What about you guys?
