PyGdalSAR
Post-processing InSAR tool package written in the Python and Gdal programming language. It can be utilizes for predictives and empirical atmospheric corrections on the unwrapped interferograms, or time series correction from the GACOS atmospheric models (ceg-research.ncl.ac.uk/v2/gacos/). Additional package for iterative spatial and temporal decompositions of geodetic Time Series (InSAR, GPS or Pixel Offsets), plotting, cleaning of interferograms or time series, radar to geographic conversions, etc...
To download the package
git clone https://github.com/simondaout/PyGdalSAR.git
To update the software:
git pull
In case of fire:
git commit
git push
leave building
Requirements
This project needs the following external components:
- CMake
- Python (2.7)
- py27-gdal
- py27-numPy
- py27-sciPy
- Gdal (https://www.gdal.org)
- docopt (Available on https://github.com/docopt/docopt or in ./python/).
- py27-matplotlib
- py27-datetime
- NSBAS (optional): http://efidir.poleterresolide.fr/index.php/effidir-tools/nsbas
Installation
- The majortiy of the scripts are written in python and do not need installation. Just add them to your PATH. If you are using module, an example of modulefile is available in /contrib/modulefile/pygdalsar
- Some C and Fortran components can be installed with CMake (http://www.cmake.org). To build and install: cmake -S . -B bin cmake --build bin
Setting specific compilers is also done the usual CMake way, for example to use gcc, gfortran and python2.7 as C, Fortran, an python compilers, do:
$ cmake -DPYTHON_EXECUTABLE=/opt/local/bin/python2.7 -DCMAKE_C_COMPILER=gcc -DCMAKE_Fortran_COMPILER=gfortran -S . -B bin
Organisation
This project contains the following folders:
- timeseries: programms for time series decomposition
- atmocorr: programms for atmospehric corrections.
- plots: plotting programms for .tiff, .r4, time series or .unw files
- utils: additional tools for cleaning .r4 or .unw formats, georeferenced formats (default: .tif), geocoding, conversion dates to decimal dates.
- src: fortrtan programms, in progress
- tutorial:
- ReversibleDeformation: example GACOS corrections, empirical phase/topo corrections and extraction of reversible derformations with seasonal functions.
- Vector: in progress
