i have 5 continental files that i want to mosaic into a global file.

i got the mosaic_doit function to run and i get all of my continents
piled up on the upper left corner. i assume that this is because my i
defined these two variables like this:

x0=[0,0,0,0,0]
y0=[0,0,0,0,0]

i assumed that this was asking for the first pixel that you want to
process in each file. apparently i was wrong. does anyone with more
experience know if this is why i'm getting all my continents piled on
top of one another?

is it possible that IDL/ENVI is asking me to place the files manually
on the map space? i guess the left-most part of the north america file
would be x0=0, y0=0, but i have no idea where austrial/eurasia,south
america/africa is! is the software really asking me to do this
manually? that would be crazy.

i have used the envi_convert_file_coordinates command before, but it
requires a reference FID. Is there a way to create a map structure
with an associated FID to use as a reference? i can then extract the
UL from each file and conver to file coordinates associated with a
global map strucutre of the same dimensions as my output file. i dont
really know what i'm talking about here with this suggestion, but
somebody else does....

any input/suggestions?

thanks.
