EXAMPLE
pdismph_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pdiff 5 08256.rmli.par average.rmli 3

Displays 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.

pdismph_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pdiff - 08256.rmli.par average.rmli 3

Displays the phases of each record of the point data stack of the differential interferogram (fcomplex) provided, using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 2PI radian phase.

pdismph_pwr24_map testsite.plist_map testsite.pmask testsite.dem_par testsite.pdiff 5 average.rmli 3

Displays the phases (in radian) of the fcomplex differential interferogram in map geometry, 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
pdismph_pwr24 and pdismph_pwr24_map are csh scripts in ./IPTA/scripts.

DESCRIPTION
pdismph_pwr24 supports the display of the phases of the complex valued (fcomplex) point data (stack of single or mutliple records) in color and the image brightness corresponding to a backscatter intensity image.

In a first step the point data are transformed to a 2 dimensional image (using the program pt2data) which is subsequently displayed using the program dismph_pwr24.

This is done either for one record or for all records. To select all records "-" is indicated instead of a record number. If all records are selected the second record is displayed as soon as the display window of the display of the first record is closed, etc.

In the display a zoom window is included and the value (fcomplex, real part, imaginary part, magnitude and phase) at the cursor location is displayed.

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).

pdismph_pwr24_map supports the display of the phases of the complex valued (fcomplex) point data (stack of single or mutliple records) in color and the image brightness corresponding to a backscatter intensity image, in map geometry. The functionality corresponds to the one of pdismph_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 pdismph_pwr24.

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