green space maps
Green space maps originate from efforts to distinguish public and private space, such as the influential map of Rome by Giambattista Nolli. In the USA, this evolved into maps that show parks and other green spaces that the public could access in towns and cities, including Olmstead’s map of Boston’s Emerald Necklace and Chevalier’s tourist map of San Francisco.
