Tube style walking maps connecting open spaces

Greenground Map is a tube-style walking map connecting parks and open spaces into a large network of creative green and blue routes. The maps aim to encourage walking and cycling along green spaces and reimagine cities through green and blue infrastructure. The project first started in the spring of 2019 when graphic designer Helen Ilus proposed an idea to connect parks in a tube-style walking map. The idea was well-received, and the first maps were collaborative, with people suggesting parks and open spaces to add.

Since then, Helen has worked with charities and councils on several commissioned maps and keeps creating her independent maps. Her newest idea, Bookground Map, connects public library spaces across London.
