It adds taxiway lights and other features to the RJOO produced and sold by MADB, so you need a paid RJOO produced by MADB.

RJOO by MADB is a great airport, but it lacks taxiway lights, so taxiway lights needed to be added.
The centerline and edge lines have been redrawn based on google maps.

Some lines, such as the lines for vehicles, are missing.

MADB's RJOO Osaka Itami Airport appears to be no longer for sale.

Additional libraries are required.

Install

Please change the folder name to be after RJOO OSAKA ITAMI AIRPORT MADB.
Example
airport-rjoo-osaka-MADB
airport-rjoo-osaka-z-enhanced

It does not change the original airport files, so please separate the folder names and do not overwrite the original airport files.
If you apply it to the default airport, the taxiway lines will be displayed twice.

It does not contain any data by MADB. It is all newly created.
