reader.abstracted_metadata

The abstracted_metadata subpackage handles all workflows related to parsing the Abstracted Metadata section that is found in Sentinel-1 metadata.

This class is not designed to be directly used by the user. It is designed for the classes in PyBeamDimap.missions.

Bases: object

property EsdMeasurement

Subclass to handle ESD Measurement section. Access this property to access ESD measurement data.

__init__(metadata, product)

  • product – Sentinel-1 Product type

property baselines: pandas.DataFrame

Dataframe object containing baseline data between two image acquisitions

property burst_boundary

Dataframe object containing burst boundary data

property dataframe: pandas.DataFrame

Dataframe object containing all non-nested abstracted metadata elements

property doppler_centroid_coeffs: pandas.DataFrame

class PyBeamDimap.reader.abstracted_metadata.EsdMeasurement(metadata, product)

Bases: object

__init__(metadata, product)

Class to handle ESD measurement properties in the abstracted metadata class

dataframe(image=None, param=None, verbose=True)

Generate a Pandas dataframe of the ESD measurements. Only one image can be loaded at a time.

Parameters

  • image – Dataset to check. Default will use first image in the dimap file.

  • param – Parameter to check. Default will use first parameter in the ESD measurement metadata
