IMGREMAP -- Remaps an image into a different projection
  IMGREMAP sdataset ddataset <keywords>
Parameters:
   sdataset | source ADDE dataset name and position; specify as
              alias.position or group/descriptor.position; to use default
              position, either enter "0" or omit .position portion
              (no def for alias or group/descriptor, def=0 for position)
   ddataset | destination ADDE dataset name and absolute position;
              specify as alias.position or group/descriptor.position;
              only positive integers are valid for the position number
Keywords:
*********************  Image Selection Keywords  *************************
  DAY= | selects the most recent sdataset image from the specified day
         (def=most recent image)
  TIMe=btime etime | selects the most recent sdataset image in the
                     specified time range (def=most recent image)
  MAG=lmag emag | line and element reduction factor to apply to source
                  data before it's remapped; valid range is 1 through -999
                  where 1, 0, and -1 mean no reduction, -2 means a 2x
                  reduction, etc; see Remarks (lmag def=1, emag def=lmag)
***************************  Output Keywords  ****************************
  BANd= | image band number (def=existing band if image is single-band;
          no def if image is multi-band)
  LATlon= clat clon | center latitude and longitude for ddataset
                      (def=center latitude and longitude of sdataset)
  STAtion= | station ID, e.g., MSN, YSSY, 72201 to place at center
             of remapped image
  MERge=YES | merge data in sdataset with what is in ddataset; valid
              only with PRO=DEST
       =NO  | overwrite data in ddataset (def)
  PRO=DEST | use the navigation of ddataset (def)
     =LAMB slat1 slat2 slon | Lambert Conformal, standard latitude
                              and standard longitude (slat1 def=30,
                              slat2 def=50, slon def=center longitude)
     =MERC slat | Mercator projection and standard latitude (slat def=0)
     =MOLL slon | Mollweide projection and standard longitude (slon def=0)
     =PS slat slon | Polar Stereographic projection, standard latitude
                     and standard longitude
                     (slat def=60, slon def=center longitude)
     =RADAR rot | Radar projection and rotation angle (rot def=0)
     =RECT | Rectilinear projection
     =SIN | Sinusoidal Equal Area projection
     =TANC slat slon | Tangent Cone projection, standard latitude and
                       standard longitude (slat def=30 if center latitude
                       is in northern hemisphere, -30 if center latitude
                       in southern hemisphere; slon def=center longitude)
  RES= | resolution of ddataset in km; not valid with PRO=DEST (def=1)
  SIZe=line ele | number of lines and elements in ddataset; the 'ele'
                  value must be a multiple of 4; SIZE is not valid with
                  PRO=DEST (def=480 640)
      =ALL      | creates an image large enough to include entire
                  geographical coverage of sdataset
  SMOoth=limb data | provide limb or data smoothing, where:
                     limb - NO or YES for limb smoothing (def=NO)
                     data - NO or YES for data smoothing (def=NO)
  SPLine= | spline size in image pixels; range is at least 1 to 100; the
            range minimum may be computed base on source data (def=20)
Remarks:
  IMGREMAP uses the sdataset parameter and the DAY and TIME keywords to
  select the source image to remap. It uses the "Output Keywords" to
  calculate the data coverage and band to extract from the source image.
  Only the source image data needed to create the destination image is
  extracted and remapped.

  The MAG keyword can be used to further reduce the amount of source image
  data that is extracted and remapped. Use the MAG keyword only when
  specifying a destination image with less detail (lower resolution) than
  the source image. For example, if the source image is 1km resolution
  and you specify RES=30 for a 30km resolution destination image, you can
  also specify MAG=-16 to reduce the amount of data extracted and remapped
  by a factor of 16. It's best to pick a MAG value somewhat less than the
  destination image resolution because the quality of the destination
  image decreases as the MAG value approaches the resolution value.

  When using PRO=DEST, both the sdataset and ddataset image must
  contain navigation. Display the new image with the command IMGDISP.
