Setup and formating for KF
**************************

Prepare inputs
==============

Format 
-------

KFTS-InSAR reads an HDF5 file containing the interferogram stack. It can contain the following dataset, although other format are suported, for *N* interferograms of (*Y*, *X*) pixels linking *M* acquisitions::

    Jmat            Dataset {N, M}     Connectivity matrix [-1,1,0]
    bperp           Dataset {N}        Perpendicular baseline array (not used by KFTS yet)
    dates           Dataset {M}        Array of ordinal values for SAR acquisition dates
    figram          Dataset {N, Y, X}  Array of interferograms 
    tims            Dataset {M}        Array of SAR acquisition times in decimal years


.. note:: KFTS is able to read ``MintPy`` ifgramStack file without the use of the `prepare_input.py` routine 

Prepare input interferogram stack [optional] 
--------------------------------------------

Preprocessing only useful if the HDF5 file discribed above has to be constructed. Functions are optimized for ISCE architecture. 

.. automodule:: prepare_input
    :members:


Read and formate data 
=====================

Processing steps contained in the main KFTS-InSAR routine. 

.. automodule:: kf.readinput
.. autoclass:: SetupKF
   :members:

Create or open storage file
===========================

Processing steps contained in the main KFTS-InSAR routine. Storage files, or outputs are described in Section 2.3. 

.. automodule:: kf.readinput
    :members: initiatefileforKF, reopenfileforKF
