for google earth, try:

mapStruct = MAP_PROJ_INIT(117, LIMIT=limit, $
CENTER_LONGITUDE=180)
PLOT, mapStruct.uv_box[[0,2]],mapStruct.uv_box[[1,3]] , $
/NODATA, ISOTROPIC=0, XSTYLE=5, YSTYLE=5,$
xtickname = blank_string(10),ytickname=blank_string(10),$
position = [0,0,1,1]


(just as a start, that may help with the "line up" problem.

cheers,
bob
