### Antarctic Iceberg Tracking Database

###	Data downloaded from https://www.scp.byu.edu/data/iceberg/stats_database_v7.1.zip and https://www.scp.byu.edu/data/iceberg/consolidated_database_v7.1.zip on 2026-03-16
    See https://www.scp.byu.edu/data/iceberg/default.html for latest version of database (last updated: 2023)
    
###	Processing steps:

    1.  Download latest version of database from https://www.scp.byu.edu/data/iceberg/default.html
    
    2.  Copy all consolidated csv files to cwd\input\consolidated\ <-- files used in Seamap Antarctica
        Copy all statistical csv files to cwd\input\statistical\
    
    3.  Consolidated iceberg tracks: Run 02_merge_csv_create_shp_consolidated.py from cwd
        * Merges all csv files from cwd\input\consolidated\
        * Appends 'iceberg_id' column matching csv filename
        * Derives latitude and longitude using sensor priority (configurable)
        * Writes merged csv to cwd\output\consolidated\
        * Generates shapefile (EPSG:3031) using derived lat/lon and writes to \output\consolidated\

    4.  Statistical iceberg database: Run 03_merge_csv_create_shp_statistical.py from cwd
        * Merges all csv files from cwd\input\statistical\
        * Appends 'iceberg_id' column matching csv filename
        * Writes merged csv to cwd\output\statistical\
        * Generates shapefile (EPSG:3031) using reported lat/lon columns and writes to \output\statistical
