I am attempting to use MAP_SET to add a satellite projection to an
image. However, the map doesn't cover the whole area. The image is 519x298
and the map only covers 0:518,0:289 ( about 10 pixels short on the top).
Can some one tell me how to get the map to fit the whole image.
lat0 = -0.340134
lon0 = -90.3042
NW_lat = 44.756
NW_lon = -109.456
NE_lat = 44.326
NE_lon = -93.063
SE_lat = 29.123
SE_lon = -92.527
SW_lat = 29.311
SW_lon = -105.340
xmval(0) = 0
xmval(1) = 0
ymval(0) = 0
ymval(1) = 0
map_set, lat0, lon0, 0, $
sat_p = [6.61128827325631,0,0], $
/Satellite, $
/USA, $
/NOERASE, $
/NOBORDER, $
Xmargin = xmval, Ymargin= ymval, $
Limit = [ NW_lat, NW_lon, $
NE_lat, NE_lon, $
SE_lat, SE_lon, $
SW_lat, SW_lon ]

An extra question , does this remapping facilitate polar orbiting
satellites.
