Subject: Sectoring GINI images
Since Tom W. mentioned sectoring/sampling the GINI
images, I wanted to let everyone know that we do have
GEMPAK program which will sector and sample the GINI
imagery.
Here is the description for program "sector".
SECTOR subsets a GINI satellite image in area and pixel resolution.
INPUT PARAMETERS
SATFIL *Satellite image filename(s)
OUTFIL *Output satellite image filename
GAREA *Graphics area
PIXRES *Resolution of output image
PROGRAM DESCRIPTION
SECTOR subsets a GINI satellite image in area and pixel
resolution. The input satellite file MUST be an AWIPS/GINI
file. The new file is created with an updated header based
on the subset area or the new number of pixels and lines.
If GAREA is DSET the entire image is used, otherwise a subset
specified by GAREA is obtained from the image. PIXRES is the
input for how many pixels and lines to include in the new
image. If PIXRES is 4, then every 4th pixel and line will be
used in the new image.
EXAMPLES
1. Create a subset image over Kansas, that uses all pixels.
SATFIL = IR_960723_1200
OUTFIL = IR_960723_1200_ks
GAREA = ks
PIXRES = 1
2. Create a new image that is for the entire area but uses
every 4th pixel and line.
SATFIL = IR_960723_1200
OUTFIL = IR_960723_1200_4
GAREA = dset
PIXRES = 4
