Global parameters for LAMS system.
These are the global parameters needed for LAMS. These globals are active during each LAMS session. Globals may be set on the command line by entering LET name=value or may be changed by tutoring LAMGBL. The global parameters OFFL, OFFS, XNL, XNS, and MEANZ may also be saved between sessions by using the routines IBIS2GBL and SETGBLS.
- $IMAGE("")
- The name of the input images to be mosaicked.
This global parameter should be set by the user within ULOGON.PDF before processing begins and should not be changed unless processing is started at the beginning of LAMS.
The number of values in $IMAGE, $INL, and $INS have to be the same. The first value of $IMAGE should correspond with the first value of $INL, and $INS and so on.
- $INL(2983)
- The number of lines in each of the input images.
This global parameter should be set by the user within ULOGON.PDF before processing begins and should not be changed unless processing is started at the beginning of LAMS.
The number of values in $IMAGE, $INL, and $INS have to be the same. The first value of $INL should correspond with the first value of $IMAGE, $INS, and so on.
- $INS(3548)
- The number of samples in each of the input images.
This global parameter should be set by the user within ULOGON.PDF before processing begins and should not be changed unless processing is started at the beginning of LAMS.
The number of values in $IMAGE, $INL, and $INS have to be the same. The first value of $INS should correspond with the first value of $IMAGE, $INL, and so on.
- $MOSIMG("")
- The name of the output mosaic.
- $MOSNL(1)
- The number of lines in the output mosaic.
- $MOSNS(1)
- The number of lines in the output mosaic.
- $MOSOFFL(1)
- The starting line of the first input image within the output mosaic. This is used to create mask at the top of the output image.
- $MOSOFFS(1)
- The starting sample of the first input image within the output mosaic. This is used to create mask at the left side of the output image.
- $MEANZ(0)
- The average radiometric value of an input image. This value is calculated and set within the procedure pdf MRAD.
- $OFFL(1)
- The line offset of an input image into the output mosaic. This value is calculated and set within the procedure pdf MCRN.
- $OFFS(1)
- The sample offset of an input image into the output mosaic. This value is calculated and set within the procedure pdf MCRN.
- $XNL(1)
- The number of lines in the transformed input image This value is calculated and set within the procedure pdf MCRN.
- $XNS(1)
- The number of samples in the transformed input image This value is calculated and set within the procedure pdf MCRN.
- $WINDOW1(-- )
- Window specifications. These are the minimum and maximum line/sample locations of the output polygons from the function INTCUT for the first input file.
- $WINDOW2(--)
- Window specifications. These are the minimum and maximum line/sample locations of the output polygons from the function INTCUT for the second input file.
The $IMAGE global is set to the values of IMAGE1 and IMAGE2 while $INL and $INS is set to the values of 1024 and 512.
The values of the global parameters used by LAMS are set according to the input parameters. These global parameters are used by and set by some of the LAMS applications.
