🔸UAVSAR#

GRD (uavsar_grd)#

The uavsar_grd function extracts matrix elements (C3 or T3) from the given UAVSAR .ann file and saves them into respective directories (C3 or T3).

polsartools.uavsar_grd(annFile, matrix='C3')[source]

Extracts specified matrix elements (C3 or T3) from a UAVSAR .ann file and saves them into respective directories (C3 or T3).

Example:#

>>> uavsar_grd("path_to_file.ann", matrix='C3')
This will extract the C3 matrix elements from the specified .ann file and
save them in the 'C3' directory.

>>> uavsar_grd("path_to_file.ann", matrix='T3')
This will extract the T3 matrix elements and save them in the 'T3' directory.

Parameters:#

annFilestr

The path to the UAVSAR annotation file (.ann) that contains the radar data metadata.

matrixstr, optional (default=’C3’)

The type of matrix to extract. Can either be ‘C3’ or ‘T3’.

  • ‘C3’ will extract the C3 matrix elements.

  • ‘T3’ will extract the T3 matrix elements.

Returns:#

None

The function does not return any value. Instead, it creates a directory (C3 or T3) and populates it with the corresponding matrix elements.

Raises:#

FileNotFoundError

If the specified .ann file does not exist or cannot be found.

ValueError

If the matrix argument is not one of ‘C3’ or ‘T3’.

MLC (uavsar_mlc)#

The uavsar_mlc function extracts matrix elements (C3 or T3) from the given UAVSAR .ann file and saves them into respective directories (C3 or T3).

polsartools.uavsar_mlc(annFile, matrix='C3')[source]

Extracts specified matrix elements (C3 or T3) from a UAVSAR .ann file and saves them into respective directories (C3 or T3).

Example:#

>>> uavsar_mlc("path_to_file.ann", matrix='C3')
This will extract the C3 matrix elements from the specified .ann file and
save them in the 'C3' directory.

>>> uavsar_mlc("path_to_file.ann", matrix='T3')
This will extract the T3 matrix elements and save them in the 'T3' directory.

Parameters:#

annFilestr

The path to the UAVSAR annotation file (.ann) that contains the radar data metadata.

matrixstr, optional (default=’C3’)

The type of matrix to extract. Can either be ‘C3’ or ‘T3’.

  • ‘C3’ will extract the C3 matrix elements.

  • ‘T3’ will extract the T3 matrix elements.

Returns:#

None

The function does not return any value. Instead, it creates a directory (C3 or T3) and populates it with the corresponding matrix elements.

Raises:#

FileNotFoundError

If the specified .ann file does not exist or cannot be found.

ValueError

If the matrix argument is not one of ‘C3’ or ‘T3’.
