Export Processed Landings Data

Exports validated landings data to a MongoDB collection. This function filters and transforms preprocessed data, calculates total catch weights, and exports selected fields to a validated collection.

Usage

export_landings()

Value

None (invisible). Data is exported directly to MongoDB.

Details

The function performs the following steps:

1. Pulls preprocessed data from MongoDB

2. Calculates total catch weights per submission

3. Filters for valid survey activities (survey_activity == 1)

4. Selects relevant fields for export

5. Uploads the filtered data to the validated collection

Note

Only submissions with survey_activity == 1 are included in the export. Catch weights are summed per submission, with NA values removed.

• submission_id: Unique identifier for the submission

• landing_date: Date and time of landing

• propulsion_gear: Type of propulsion

• trip_duration: Duration of fishing trip

• gear: Fishing gear used

• catch_df: Nested catch data
