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 Chiz
