EXAMPLE
pdisdt_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pdef 1 08256.rmli.par average.rmli 0.01 3

Displays the real valued point data (deformation rates in m/year) using the average backscatter intensity image for the image brightness and a colors with a cycle corresponding to 1 cm/year for the deformation.

pdisdt_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.phgt 1 08256.rmli.par average.rmli 500. 3

Displays the real valued point data (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.

pdisdt_pwr24 testsite.plist testsite.pmask 08256.rslc.par testsite.pres - 08256.rmli.par average.rmli 6.28. 3

Displays each record of the point data stack of residual phases (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.

pdisdt_pwr24_map testsite.plist_map testsite.pmask testsite.dem_par testsite.pdef 1 average.rmli 0.01 3

Displays the real valued point data (deformation rates in m/year) in map geometry, 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
pdisdt_pwr24 is a csh script in ./IPTA/scripts.

DESCRIPTION
pdisdt_pwr24 supports the display of real valued 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 disdt_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 (float) at the cursor location (float) 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).

pdisdt_pwr24_map supports the display of real valued 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 pdisdt_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 pdisdt_pwr24.

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