## Folder "mapped_by_flag_country_industrial"
Contains country tables for the gridded (1 degree cell) effort. Years span 1950-2017, as appropriate.
Filenames as follow: model_preds_1950_2017_{flag_country_iso3c}.csv
flag_country_iso3c is the ISO3 Country Code. 
Each row is one fishing effort event (effort by fishing country, vessel length category, gear type, year, and sector)
The effort is in kW x days at sea and kW x hours at sea, and provides a pixel size to calculate per km2 effort.
