MASK-Uses an ARD file to set some pixels of a given image to bad
- Description:
Allows the user to input the name of an NDF image file and
and ARD file. The ARD file is used to specify which parts of the
image will NOT be used. An output NDF is then created which is
the same as the input file except that all pixels specified by
the ARD file have been assigned the value Bad.
- Usage:
MASK IN ARDFIL OUT
- Parameters:
-
ARDFIL = _CHAR (Read)
-
The name of the ARD file containing a description of
the parts of the image to be masked out i.e. set to bad.
-
IN = _NDF (Read)
-
The name of the source NDF.
-
OUT = _NDF (Write)
-
The name of the output NDF.
- Examples:
-
mask in=ic3374 ardfil=
ardfile.txt out=ic3374a
-
This example uses as the source image IC3374 and sets
the pixels specified by the ARD description contained in
ARDFILE.TXT to the bad value. The resultant image is output
as IC3374A.
