positional arguments:¶

timeseries_file

Timeseries file to be corrrected

options:¶

-h, --help

show this help message and exit

-g GEOM_FILE, --geometry GEOM_FILE

geometry file including datasets: incidence angle slant range distance and/or 3D perpendicular baseline

-o OUTFILE, --outfile OUTFILE

Output file name for corrected time-series

--phase-velocity

Use phase velocity instead of phase for inversion constrain.

--update

Enable update mode, and skip inversion if: 1) output timeseries file already exists, readable and newer than input interferograms file 2) all configuration parameters are the same.

--ram MAXMEMORY, --memory MAXMEMORY

Max amount of memory in GB to use (default: 4.0). Adjust according to your computer memory.

temporal deformation model:¶

-t TEMPLATE_FILE, --template TEMPLATE_FILE

template file with the options

--ex [EXCLUDEDATE ...], --exclude [EXCLUDEDATE ...]

Exclude date(s) for DEM error estimation. All dates will be corrected for DEM residual phase still.

-p POLYORDER, --poly-order POLYORDER

polynomial order number of temporal deformation model (default: 2).

-s [STEPFUNCDATE ...], --step-date [STEPFUNCDATE ...]

Date of step jump for temporal deformation model (default: []). i.e. date of earthquake/volcanic eruption

--periodic PERIODIC [PERIODIC ...], --period PERIODIC [PERIODIC ...], --peri PERIODIC [PERIODIC ...]

periodic functinos of temporal deformation model (default: []).

parallel:¶

parallel processing using dask

-c {lsf,pbs,slurm,local}, --cluster {lsf,pbs,slurm,local}, --cluster-type {lsf,pbs,slurm,local}

Cluster to use for parallel computing (default: None to turn OFF).

--num-worker NUMWORKER

Number of workers to use (default: 4).

--config CONFIG, --config-name CONFIG

Configuration name to use in dask.yaml (default: None).

template options:¶

## Topographic residual (DEM error) correction ## reference: Fattahi and Amelung (2013, IEEE-TGRS) ## stepFuncDate - specify stepFuncDate option if you know there are sudden displacement jump in your area, ## e.g. volcanic eruption, or earthquake ## excludeDate - dates excluded for the error estimation ## pixelwiseGeometry - use pixel-wise geometry (incidence angle & slant range distance) ## yes - use pixel-wise geometry if they are available [slow; used by default] ## no - use the mean geometry [fast] mintpy.topographicResidual = auto #[yes / no], auto for yes mintpy.topographicResidual.polyOrder = auto #[1-inf], auto for 2, poly order of temporal deformation model mintpy.topographicResidual.phaseVelocity = auto #[yes / no], auto for no - phase, use phase velocity for minimization mintpy.topographicResidual.stepFuncDate = auto #[20080529,20190704T1733 / no], auto for no, date of step jump mintpy.topographicResidual.excludeDate = auto #[20070321 / txtFile / no], auto for exclude_date.txt mintpy.topographicResidual.pixelwiseGeometry = auto #[yes / no], auto for yes, use pixel-wise geometry info
