Would it be plagiarism if I used the London Underground map (tube map) in a new App I'm making??

It would be illegal without permission because it is copyrighted.

“London Underground is the world's oldest and best known metro system. “The present Tube map created by Harry Beck in 1931 is a design classic and has been the inspiration for metro maps throughout the world. “Transport for London holds the copyright for both the world famous Underground roundel and Tube map.
