eodal.metadata.sentinel2.database.ingestion.meta_df_to_database(meta_df: DataFrame, raw_metadata: bool | None = True) → None[source]

Once the metadata from one or more mapper have been extracted the data can be ingested into the metadata base (strongly recommended).

This function takes a metadata frame extracted from “raw” or “processed” (i.e., after spatial resampling, band stacking and merging) Sentinel-2 data and inserts the data via pandas intrinsic sql-methods into the database.

Parameters:

  • meta_df – data frame with metadata of one or more mapper to insert

  • raw_metadata – If set to False, assumes the metadata is about processed products

eodal.metadata.sentinel2.database.ingestion.metadata_dict_to_database(metadata: dict) → None[source]

Inserts extracted metadata into the meta database

Parameters:

metadata – dictionary with the extracted metadata

eodal.metadata.sentinel2.database.ingestion.update_raw_metadata(meta_df: DataFrame, columns_to_update: List[str]) → None[source]

Function to update one or more atomic columns in the metadata base. The table primary keys ‘scene_id’ and ‘product_uri’ must be given in the passed dataframe.

Parameters:

  • meta_df – dataframe with metadata entries to update. Must contain the two primary key columns ‘scene_id’ and ‘product_uri’

  • columns_to_update – List of columns to update. These must be necessarily atomic attributes of the raw_metadata table.
