eodal.metadata.sentinel2.utils.identify_updated_scenes(metadata_df: DataFrame, return_highest_baseline: bool | None = True) → Tuple[DataFrame, DataFrame][source]

Returns those S2 entries in a pandas DataFrame retrieved from a query in eodal’s metadata base that originate from the same orbit and data take but were processed by different PDGS Processing Baseline number (the ‘Nxxxx’ in the product_uri entry in the scene metadata or .SAFE name).

Parameters:

  • metadata_df – dataframe from metadata base query in which to search for mapper with the same sensing date and data take but different baseline versions

  • return_highest_baseline – if True (default) return those mapper with the highest baseline. Otherwise return the baseline most products belong to

Returns:

Tuple with two entries. The first entries contains a DataFrame with those S2 mapper belonging to either the highest PDGS baseline or the most common baseline version. The other “older” mapper are in the second tuple item.
