Help with map types please.

Does anyone have a link to a site or a list that has a small bit of into on the maps in Civ5?

I'm asking because I really dont like playing on the maps that have borders from east to west, I prefer the ones that are wrapped with no hard borders.

any info would be appreciated.

All of the randomly generated maps (Including Earth) have wrapped borders, all of the presets (like Mesopotamia) have hard borders.

If just some images are enough for you, then take a look here http://civwiki.de/wiki/Kartensammlung_(Civ5) (might need some time for loading).
There's a similar version on the 2Kgames wiki, see here http://wiki.2kgames.com/civ5/index.php/Advanced .
