Zooming in on Big Maps

Hey All,

I am trying to zoom in on a map I have created in Photoshop.. it's quite big, as I have to show the whole of Europe, then the camera zooms into a location in Ireland.

So I have made the map 14000 x 10000. So I can zoom in nice and close with out losing resolution. I am scaling the map rather than using a 3d camera to save on memory.. however it is a 3d layer as I am skewing it a bit..

However poor old AE can't allocate space for a 14000 x 10000 image buffer. So it can't render !!

I am a bit stumped now.. I am thinking the only way for me to do this would be to take it into XSI and do it in 3d.. then try and export the camera.. however I have loads fo these to do and would rather do them in After Effects..

Has any one got any bright ideas.. maybe a different way of doing this ?

Any help would be greatly appreciated.. and sorry to bother you on the weekend..

thanks in advance

Alex
