This R Markdown document is designed to transform data that is not in CWP format into CWP format. Initially, it changes the format of the data; subsequently, it maps the data to adhere to CWP standards. This markdown is automatically created from the function: https://raw.githubusercontent.com/firms-gta/geoflow-tunaatlas/master/R/tunaatlas_scripts/pre-harmonization/west_pacific_ocean_catch_5deg_1m_ps_tunaatlaswcpfc_level0.R, the documentation keeps the format of roxygen2 skeleton.
A summary of the mapping process is provided. The path to the dataset is specified. You will find on this same repository on GitHub the first line of each dataset. The datasets are named after the historical name provided by tRFMOs while exporting and may change. The information provided in the Rmd allows understanding correctly which dataset should be used in this markdown.
Additional operations are performed next to verify other aspects of the data, such as the consistency of the geolocation, the values, and the reported catches in numbers and tons.
If you are interested in further details, the results and codes are available for review.
Each .Rmd script requires the user to knit the
dataset at the beginning of the script in order to execute the
harmonization process correctly. It is also possible to run the code
chunk by chunk but be sure to be in the correct working directory (i.e.,
the one of the .Rmd).

Harmonize WCPFC Purse Seine Catch Datasets
This function harmonizes WCPFC Purse Seine catch datasets for integration into the Tuna Atlas database, ensuring data compliance with specified format requirements.
@return None; the function outputs files directly, including harmonized datasets, optional metadata, and code lists for integration within the Tuna Atlas database.
@details This function modifies the Purse Seine catch dataset to ensure compliance with the standardized format, including renaming, reordering, and recalculating specific fields as necessary. Metadata integration is contingent on the intended use within the Tuna Atlas database.
