Table sized map of Khorvaire?

[Invader]

My PC's will be traveling across Khorvaire quite a bit and I'd like to be to give them a large detailed map of the entire continent. I've found a few good ones online but I'd like to enlarge it to roughly 4ft by 4ft so it serves as a backdrop for the campaign and in afraid it'll lose all of its detail if I make it that large.

Does anyone know how I can acomplish this?

Which image are you using? The 4th ed Eberron maps are ususally pretty large, they might be the best to scale up. Here's the Khorvaire map (http://cdn.obsidianportal.com/map_images/784786/D_D_-_4th_Edition_-_Eberron_Map_Khorvaire.jpg) if you don't already have it.

As for programs, I've had some success with this online processor (http://www.picresize.com/), but I've never tried enlarging things to that scale. Hmm, didn't seem to work for me at all using the image I linked above.

Edit: I tried a free program called SmillaEnlarger (http://sourceforge.net/projects/imageenlarger/?source=dlp), and it seemed to work well. Not sure what type of quality you're looking for though. I enlarged this map of Khorvaire (http://www.wizards.com/dnd/images/eb_map/Eberron_Map_11x17.jpg) to 7471 pixels in width, which is approximately 99 inches. If you use the program, make sure you use the sharpen option. It works wonders.

If you print out the map here (http://www.wizards.com/default.asp?x=dnd/ebwe/20041206a) on the 8 sheets of 8.5"x11" paper, you end up with a map roughly 2' 10" x 1' 10". A fair bit smaller than what you're looking for, but it does come out very nice; I did so myself.

This map (http://images.community.wizards.com/community.wizards.com/user/tireswing/large/ca8e41726b0d5373f2d53329ec97ed4f.jpg) has a similar resolution the Wizards one, but much crisper details. It might respond better than the Wizards version if you were to blow it up to double size or something.

There's a PDF map here (http://sancus.off.net/Eberron_Khorvaire_Map_1.3.pdf). It's not the prettiest, but it should scale well.

I've found both the maps you guys suggested and in def using omw if then just not sure which one yet. Thanks for the tips, I'll experiment a little bit tonight with your suggestions to see what I can get to work.

Some great maps here, considering printing one of these for the Eberron game I'm in (assuming I can do it under $20 or so).

If you can find a printing company that has a large format printer and laminator, It might actually be worth the investment should you expect to visit Khorvaire in more than one campagin.
