1) The user can specify the type of compositing that s/he wants to use. GOESCOMP will do one of two types of compositing:

C (Complex)

Image is created by using REMAP to remap the GOES-West image into the "standard" projection, then REMAPing the GOES-East image into a copy of an image that is the right (eastern) half of the "standard" projection, then MC is used to join the two REMAPed images together into the output area. (default)

S (Simple)

Image is created using REMAP to remap the GOES-West image into the "standard" projection, then uses REMAP with the MERGE=YES keyword to merge the GOES-East image into the REMAPed GOES-West image.

2) GOESCOMP may be run for products not specified in the routing table, ROUTE.SYS. In this case, the scratch area number is also the output area number.

3) Use NONE as a place holder for the ROUTE positional parameters (ie 'p1', 'p2') if you don't want to use the ROUTEing system to determine the output AREA file number or if you want to save only the image/TOPO composites.

4) GOESCOMP can be run out of ROUTE Post-Process BATCH files (ex: IR8.BAT, VIS9.BAT). Used this way, it will create the output image from the first image to arrive (GOES-West), and finish the compositing when the second image (GOES-East) arrives. The algorithm is based on the assumption that the GOES-West image arrives first, then the GOES-East image. That is how the data are transmitted on the Unidata/Wisconsin datastream. In this scenario, you would specify NONE as the value for the missing image. When the GOES-West image arrives, it is REMAPed into the "standard" projection and saved in the appropriate AREA determined by the system key table. When the GOES-East image arrives, the time from the current AREA listed in the system key table for this particular type of image is retrieved and compared against the time of the GOES-East image. If they are the same, then the GOES-East image is composited with it. If not, the GOES-East image is just REMAPed into the "standard" projection. When used this way, ssss must be the same in each pair of BATCH files (ex: IR8.BAT and IR9.BAT), and different between BATCH files of different types of images (ex: IR8.BAT and VIS8.BAT).
