http://www.h-schmidt.net/map/First download the zip file, after that you can mixed all the pictures 36x24= 864 (1200x900 pixels each).
it's not easy to make them all in one picture, but you can for exampel make it in 2 or 3 levels
1st level : make 4x3 = 12 pictures in one. you get one picture with 4800*2700
do the same thing with the other picture until you get 9*8=72 pictures.
2nd level : make 3x2 =6 pictures in one. each picture 4800*2700. so you get at the end 3x4 = 12 pictures each picture 14400*5400.
for me i have 12 Go RAM i can't get 43200*21600 so i have reduced it in half and get one big picture with 21600*10800 but still can't get animation with after effects he crash and he don't accept this hight resolution (the max : 21600*10800 ) ggrgrgrgrgr
i will show you the result soon.
