EXAMPLE
pdis2dt testsite.plist testsite.pmask 08256.rslc.par testsite.pdef1 1 testsite.pdef2 1 08256.rmli.par 0.01 3

Alternating display of two real valued point data sets (deformation rates in m/year) with the color cycle corresponding to 1 cm/year for both deformation images.

pdis2dt testsite.plist testsite.pmask 08256.rslc.par testsite.pdh1 1 testsite.pdh2 1 08256.rmli.par 5.0 3

Alternating display of two real valued point data sets (height correction values in m) with the color cycle corresponding to 5 m for both images.

pdis2dt testsite.plist testsite.pmask 08256.rslc.par testsite.pres 11 testsite.pres 13 08256.rmli.par 12.56. 3

Alternating displays of records 11 vand 13 of the point data stack of residual phases (in radian) with a color cycle corresponding to 4PI for the unwrapped phases.

pdis2dt_map testsite.plist_map testsite.pmask testsite.dem_par testsite.pdef1 1 testsite.pdef2 1 0.01 3

Alternating display of two real valued point data sets (deformation rates in m/year) in map geoemtry with the color cycle corresponding to 1 cm/year for both deformation images.

INSTALLATION
pdis2dt and pdis2dt_map are csh scripts in ./IPTA/scripts.

DESCRIPTION
pdis2dt supports the display of real valued point data (stack of single or multiple records) in color.

In a first step the point data are transformed to a 2 dimensional image (using the program pt2data) which is subsequently displayed using the DISP program dis2hgt.

Clicking the right mouse button (or clicking to the button in the corresponding window) permits to change between the display of the first and second image displayed.

In the display a zoom window is included and the values of both images (float) at the cursor location (float) are displayed.

The (multi-look) geometry used for the display is the one defined in the SLC/MLI parameter file.

pdis2dt_map supports the display of real valued point data (stack of single or multiple records) in color in map geometry. The functionality corresponds to the one of pdis2dt 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 pdis2dt.

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