Example

The example below copies a GOES satellite image and remaps it into a Mercator projection in local area 6000.

IMGCOPY GOES/VIS.5 LOCAL/AREA.6000 STA=KLAX SIZE=480 640 STYPE=VISR BAND=1

This entry copies the image in position 5 in the dataset GOES/VIS to position 6000 in dataset LOCAL/AREA. The STYPE=VISR keyword converts the image to 1-byte data with source type VISR and calibration type BRIT.

IMGCHA LOCAL/AREA.6000 ELE=1 LIN=1 RES=8 8

This entry sets the appropriate line and element resolutions and coordinates for the desired projection.

MAKNAV 6000 MERC=2000 2000 0 90 1

This entry generates a Mercator projection codicil entry for local area 6000.

IMGREMAP GOES/VIS.5 LOCAL/AREA.6000 PRO=DEST

This entry remaps the image in position 5 in the dataset GOES/VIS into position 6000 in dataset LOCAL/AREA.
