BMP vs Vector Graphics

Hello everyone,

I have to animate a HUGE map for a project (a 1500 px square).
I have to import it from Illustrator CS2.
Once imported in Flash, I can see alot
of symbols attached to it. It’s all vector…

Which format is best to animate the map?
(tween left to right, zoom)

Is there a way to flatten the map that would make only one symbol?

Any ideas are welcome…
