EXAMPLE
rasdt_pwr24 testsite.def testsite.rmli 1000 1 1 0 1 1 0.01
1. .35 -1 08256_08757.def.ras
Generates an 24-bit SUN rasterfile of the real valued deformation (in m/year) rates using the backscatter intensity image for the image brightness and a colors with a cycle corresponding to 1 cm/year for the deformation.
rasdt_pwr24 testsite.hgt testsite.rmli 1000 1 1 0 1 1 100. 1. .35 -1 08256_08757.def.ras
Generates an 24-bit SUN rasterfile of the real valued height (in meters) using the backscatter intensity image for the image brightness and a colors with a cycle corresponding to 100 m for the heights.
INSTALLATION
Source code rasdt_pwr24.c in ./IPTA/src, executable version
rasdt_pwr24 in ./IPTA/bin
DESCRIPTION
rasdt_pwr24 supports the generation of a 24-bit SUN/BMP raster
file image of a real valued image 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 color (deformation rate, height, ...) 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.
If a minus - is specified for the intensity image, then the background image will be 0 where the input data is 0, otherwise a constant intensity image is generated of the parameter.
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.
