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:¶
- file
- Ascending and descending files Both files need to be geocoded in the same spatial resolution.
options:¶
- -h, --help
- show this help message and exit
- -d DS_NAME, --dset DS_NAME
- dataset to use, default: 1st dataset
- -g GEOM_FILE GEOM_FILE, --geom-file GEOM_FILE GEOM_FILE
- Geometry files for the input data files.
- --max-ref-yx-diff MAX_REF_YX_DIFF
- Maximum difference between REF_Y/X (derived from REF_LAT/LON) of input files (default: 3).
- --az HORZ_AZ_ANGLE, --horz-az-angle HORZ_AZ_ANGLE
- 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
- Set to the azimuth angle of the strike-slip fault to measure the fault-parallel displacement.
- Note: a. This assumes no deformation in its perpendicular direction b. Near north direction can not be well resolved due to the lack of
- diversity in viewing geometry. Check exact dilution of precision for
- each component in Wright et al. (2004, GRL)
- -o HZ_FILE UP_FILE, --output HZ_FILE UP_FILE
- output file name for vertical and horizontal components
- --oo ONE_OUTFILE, --one-output ONE_OUTFILE
- Stack the input/output files into one HDF5 file. This will disable the HZ/UP_FILE output option.
