NAME

mintpy-asc_desc2horz_vert - Project Asc and Desc LOS displacement to Horizontal and Vertical direction

DESCRIPTION

usage: asc_desc2horz_vert.py [-h] [-d DS_NAME] [-g GEOM_FILE GEOM_FILE]

[--max-ref-yx-diff MAX_REF_YX_DIFF]
[--az HORZ_AZ_ANGLE] [-o HZ_FILE UP_FILE] [--oo ONE_OUTFILE] file file

Project Asc and Desc LOS displacement to Horizontal and Vertical direction

positional arguments:

Ascending and descending files Both files need to be geocoded in the same spatial resolution.

options:

show this help message and exit
dataset to use, default: 1st dataset
Geometry files for the input data files.
Maximum difference between REF_Y/X (derived from REF_LAT/LON) of input files (default: 3).
Azimuth angle in degrees of the interested horizontal direction (default: -90.0). Measured from the north with positive for anti-clockwise direction. E.g.: -90 for East direction
0
for North direction
Note: a. This assumes no deformation in its perpendicular direction b. Near north direction can not be well resolved due to the lack of
each component in Wright et al. (2004, GRL)
output file name for vertical and horizontal components
Stack the input/output files into one HDF5 file. This will disable the HZ/UP_FILE output option.
