Perl Script: mk_mli_all
NAME
mk_mli_all - Calculate MLI images generate multi-temporal MLI
from a set of SLCs
SYNOPSIS
]
mk_mli_all <SLC_tab> <MLI_dir> <rlks>
<azlks> [sflag] [scale] [exp] [MLI_ave
<SLC_tab> | (input) two column list of SLC filenames and SLC parameter filenames (including paths) (ascii) |
<MLI_dir > | (input) directory to contain MLI images and MLI image parameter files |
<rlks> | range looks for the MLI images |
<azlks> | azimuth looks for the MLI images |
<sflag> | MLI image average flag: 0: no (default) 1: yes |
[scale] | relative intensity display scale factor (default =
0.7) |
[exp] | display exponent (default = 0.35) |
[MLI_ave] | MLI average image filename (without path), file is
copied into the MLI_dir |
-s scale | MLI radiometric scale factor, nominal value for calibrated SCOMPLEX HH and VV data: 1.e-6 |
EXAMPLE
mk_mli_all SLC_tab mli_1_5 1_5 0 .7
.35
Generates a set of mli images from a set of SLC images listed in the SLC_tab file. The multi-look intensity (MLI) images with extension mli are are placed in the mli_1_5 directory. These are produced using the ISP program multi_look.
A raster image is produced from each mli image. The DISP
program raspwr is used to make an 8-bit Sun Raster format image
using a relative scale factor of 0.7 and exponent of 0.35.No
average mli image is produced.
mk_mli_all
RSLC_tab rmli_1_5 1_5 1 .7 .35
hector_ave.rmli
Generates a set of rmli images from a set of
coregistered and resampled SLC images listed in the RSLC_tab
file. The RMLI images with extension rmli are are placed in the
rmli_1_5 directory. These images are produced using the ISP
program
multi_look. A radiometric scale factor is applied to
the MLI images of 1.e-6 because the input images are SCOMPLEX
formation
The DISP program raspwr is used to make an 8-bit raster format
(BMP or Sun Raster) using a default relative scale factor of 0.7
and exponent of 0.35. The rmli images are averaged and stored
in the file hector_ave.rmli. The average image is produced using
the ISP program ave_image.
DESCRIPTION
The Perl script mk_mli_all takes as input a two
column list of SLC images and image parameter files with an
example shown below for 2 SLC images.

SLC_tab
slc/19990915.slc
slc/19990915.slc.par
slc/19991020.slc
slc/19991020.slc.par
A way to produce this list is to use the DIFF script
called mk_tab. As
a prerequisite all the SLC images should be located in the same
directory. The usage of mk_tab is:
$ mk_tab

usage:
/home/cw/GPRI2/trunk/software/mk_tab <dir> <ext-1>
<ext-2> <tab>
dir
(input) directory including paths that contain the data files
ext-1 (input) pattern to select data files
(examples: slc, raw...), (enter - for all files in the
directory)
ext-2 (input) pattern to select parameter
files that match the data (enter - for none, examples:
slc.par, raw_par, raw.par)
tab (output) list of data
filenames and associated parameter files (including paths)
(text)
NOTE: The current
directory is denoted using .
The files listed in column 1 of the output tab file
has the extension specified by the ext-1 command line parameter and
column 2 has the value specified by the ext-2 parameter. Output is written
to the tab file listed on the command line. The output of
mk_tab is written to the
output tab file. To generate the SLC_tab in the examplemk_tab slc slc slc.par
