./applygacos.py inpfilename ztd1filename ztd2filename elevfilename
inpfilenmae : input interferogram, a inpfilename.rsc is needed!
ztd1filename: input GACOS ztd day1 filename, a ztd1filename.rsc is needed!
ztd2filename: input GACOS ztd day2 filename, a ztd2filename.rsc is needed!
elevfilename: elevation angle file, must be the same size with interferogram
elevation=90-incidence
can be generated by look_vector in gamma
outputfile will be saved as inpfilename.gacos
!!Note, python3 is needed!!

InSAR SBAS Time Series Tool

3 minute read

Published:

The program is written in C++ enabling multiprocessing through OPENMP. The time series inversion is calculated by a general Gauss-Markov linear model (e.g., weighted least square) and then filtered in the frequency domain by FFTW. The estimation is run on a pixel-by-pixel basis and each pixel can be estimated in parallel, therefore it is expected to run fast when OPENMP is enabled.

InSAR robust stacking tool

Published:

This is a InSAR time series analysis tool based on simple stacking with robust least squre (to delete outliers), including phase closure check (unwrapping error) and orbital ramp removal.
