GOESCOMP

Composite GOES-East/West images and optionally run NORTMAPR.


Format

GOESCOMP west east scratch type p1 p2 <keywords>


Parameters


Keywords:


Remarks

Default AREA files used:
AREA9019
TOPOgraphy image of the Western Hemisphere from 1N to 90N, satellite projection centered at 100W for creating TOPO composite
AREA9980
Scratch AREA for creating TOPO with burned in map
AREA9981
Scratch AREA containing image REMAPed into 9983
AREA9982
AREA containing the navigation information of AREA9019
AREA9983
AREA containing the navigation information for the eastern half of AREA9019
AREA9984
Scratch output AREA file from NORTMAPR

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.

Example:
 
GOESCOMP 131 151 2001

will create a composited image (using the complex method) in AREA2001.

NORTMAPR.MCB will not be run, but can easily be run manually.

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.

Example:
GOESCOMP 131 151 9987 C NONE N7

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).

Examples (from IR8.BAT, IR9.BAT):

IR8.BAT:
GOESCOMP NONE %2 9986 C CI N7 MAPAREA=YES 9970

IR9.BAT:

GOESCOMP %2 NONE 9986 C CI N7 MAPAREA=YES 9970
