Hi all,

I'm trying to deal with a pre-projected polar stereographic image with
this geometrical characteristics:

# It is a 1121x881 polar stereographic grid.
# Point (1,1) is at 23.117N 119.023W.
# Point (1,881) is at 53.509N 134.039W.
# Point (1121,1) is at 19.805N 80.750W.
# Point (1121,881) is at 45.619N 59.959W.
# The y-axis is parallel to 105W.
# The resolution is 4.7625km at 60N.
# The pole point is (I,J) = (400.5,1600.5)

I don't know how may I set the map_set routine to fit the map with the
data. Is it possible to work with pre-projected data?
On the other hand, can I change the projection to a regular lat-lon
grid in IDL?
Thanks!
