EXAMPLE
rasmph_pwr24 08256_08757.diff 08256.rmli 1000 1 1 0 1 1 1.
.35 -1 08256_08757.diff.ras
Generates an 24-bit SUN rasterfile of the complex valued differential interferogram using the backscatter intensity image for the image brightness.
INSTALLATION
Source code rasmph_pwr24.c in ./IPTA/src, executable version
rasmph_pwr24 in ./IPTA/bin
DESCRIPTION
rasmph_pwr24 supports the generation of a 24-bit SUN/BMP raster
file image of the phase of a complex valued interferogram
displayed in color and the image brightness corresponding to a
backscatter intensity image.
In the frame of an IPTA investigation the use of a 24-bit SUN/BMP raster file may be an advantage due to the higher visibility of fine details in the phase and intensity information.
For areas of low coherence (below the indicated threshold), the color is suppressed and the corresponding intensity is displayed in grey. This avoids the high "color noise" of low coherence areas.
Optionally, a sub-section of the entire image, multi-looking in range and azimuth direction, or a left/right flipping can be indicated.
OPTIONS
none.
