🔸ISRO ASAR#

RSLC (`isro_asar`)#

The isro_asar function extracts S2/C3/C4/T3 matrix elements from the given ASAR RSLC .h5 file and saves them into a directory.

polsartools.isro_asar(inFile, matrixType='C3', azlks=22, rglks=10, outType='tif', max_workers=None, geocode_flag=False, calibration_constant=42)[source]

Extracts the S2/C3/T3 matrix elements from a ASAR RSLC HDF5 file and saves them into respective binary files.

Example:#

>>> nisar_rslc("path_to_file.h5", azlks=30, rglks=15)
This will extract T3 matrix elements from the specified ASAR RSLC file
and save them in the respective folders.

Parameters:#

inFilestr: The path to the ASAR RSLC HDF5 file containing the radar data.
azlksint, optional (default=8): The number of azimuth looks for multi-looking.
rglksint, optional (default=6): The number of range looks for multi-looking.
matrixTypestr, optional (default = T3): Type of matrix to extract. Valid options are ‘S2’, ‘C3’, and ‘T3’.

Returns:#

None: The function does not return any value. Instead, it creates a folder named C2/S2/C3/T3 (if not already present) and saves the following raster files:

Raises:#

Exception: If the RSLC HDF5 file is invalid or cannot be read.
