EXAMPLE
prasdt_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pdef 1 08256.rmli.par average.rmli 0.01 3

Generates an 24-bit SUN rasterfile of the real valued deformation (in m/year) rates using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 1 cm/year for the deformation.

prasdt_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.phgt 1 08256.rmli.par average.rmli 500. 3

Generates an 24-bit SUN rasterfile of the real valued heights (in m) using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 500 m for the height.

prasdt_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pres - 08256.rmli.par average.rmli 6.28. 3

Generates for each record of the point data stack of residual phases an 24-bit SUN rasterfile (in radian) using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 2PI for the unwrapped phases.

prasdt_pwr24_map testsite.plist_map testsite.pmask testsite.dem_par testsite.pdef 1 average.rmli 0.01 3

Generates an 24-bit SUN rasterfile in map geometry of the real valued deformation (in m/year) rates using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 1 cm/year for the deformation.

INSTALLATION
prasdt_pwr24 and prasdt_pwr24_map are csh scripts in ./IPTA/scripts.

DESCRIPTION
prasdt_pwr24 supports the generation of 24-bit SUN/BMP raster files for real valued point data (stack of single or mutliple records) displayed in color and the image brightness corresponding to a backscatter intensity image.

In a first step the point data is transformed to a 2 dimensional image (using the program pt2data) which is subsequently used to generate a SUN rasterfile (using the program rasdt24_pwr.

This is done either for one record or for all records. To select all records "-" is indicated instead of a record number.

The name of the output SUN rasterfile is generated from the name of the input data stack, the record number and .ras (e.g. testsite.pres.06.ras).

The (multi-look) geometry used for the display is the one defined in the SLC/MLI parameter file. For the image brightness the 2D image provided is used (which is already in the 2D multi-look geometry).

prasdt_pwr24_map supports the generation of 24-bit SUN/BMP raster files in map geometry for real valued point data (stack of single or mutliple records) displayed in color and the image brightness corresponding to a backscatter intensity image. The functionality corresponds to the one of prasdt_pwr24 with the exception that the point list indicated contains the map coordinates (pixel numbers), as obtained using the program pt2geo and the DEM/MAP parameter file is indicated instead of the SLC/MLI parameter files. The actual point data stack is the same as used by prasdt_pwr24.

OPTIONS
Additional characteristics of the resampling to 2D and the SUN rasterfile generation can be modified by editing the shell script.
