Extracting the list of coordinates for geographic role 'airport' out of Tableau

Don't they say a picture is a thousand words? All you have to do is navigate to 

C:\Program Files\Tableau\Tableau Public 2019.2\local\data

(modify appropriately for Tableau desktop). Copy the airport tableau source and the GEOCODING database into another folder, drag and drop the tds on tableau and voila, you have the airports and their coordinates! You can even export them to csv for general purpose use.
