EXAMPLE
prasmph_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pdiff 5 08256.rmli.par average.rmli 3

Generates an 24-bit SUN rasterfile of the phases (in radian) of the fcomplex differential interferogram provided as record 5 of the point data stack, using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 2PI radian phase.

prasmph_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pdiff - 08256.rmli.par average.rmli 3

Generates 24-bit SUN rasterfiles of the phases (in radian) of the fcomplex differential interferogram provided (all records) of the point data stack, using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 2PI radian phase.

prasmph_pwr24_map testsite.plist_map testsite.pmask testsite.dem_par testsite.pdiff 5 average.rmli 3

Generates an 24-bit SUN rasterfile in map geometry of the phases (in radian) of the fcomplex differential interferogram provided as record 5 of the point data stack, using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 2PI radian phase.

INSTALLATION
prasmph_pwr24 and prasmph_pwr24_map are csh scripts in ./IPTA/scripts.

DESCRIPTION
prasmph_pwr24 supports the generation of 24-bit SUN/BMP raster files for complex valued (fcomplex) 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.pdiff.05.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).

prasmph_pwr24_map supports the generation of 24-bit SUN/BMP raster files in map geometry for complex valued (fcomplex) 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 prasmph_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 prasmph_pwr24.

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