Subject: Re: [MAPS-L] Can world maps be centered on varying coordinates

Bojana,
We are definitely used to seeing world maps with the left margin at W
180 degrees and E 180 degrees. But there's no rule that says a
cartographer has to have the map with the Atlantic Ocean in the center
of the map. So it's entirely possible that the record is correct and the
cartographer used a different center point to more adequately display
what they wanted to get across. The "usual" way of doing a world map
does split the Pacific Ocean in half so if they wanted the Pacific Ocean
whole, they'd have to not do the "usual".
There's some sentiment that the "usual" way of displaying the world
emphasizes a Western bias and there are several interesting articles
about this. It even got mentioned in the television series "The West Wing"!

Hi All,
I’m a newbie map cataloger and I have a question about world maps
centered on “atypical” coordinates. I have a map:
Chart of limits of seas and oceans (publ. by Aeronautical Chart and
Information Center in 1953).
In a copy record, the left margin longitude is stated as W 90°, and the
right margin longitude is W 90°. (ocm77050953).
Can this be right or is this a cataloging error? Wouldn’t you expect a
world map to have longitudinal coordinates at W 180° degrees and E
180°?
Or is it the case that a world map can be*centered* in any longitude
that better serves the cartographer’s purpose?
Thanks for any feedback you have on this J
Bojana
