Green corridors add to the greenspace within our urban areas and enhance the opportunities for sustained ‘immersion’ in green environments. Although we would like to extend the tool to cover these, we are currently not able to as they are so varied in their form and quite difficult to accurately map. Green roofs are similarly difficult to accurately map but also generally inaccessible to people, therefore the demand model approach doesn’t work. Beaches are not green spaces and therefore lie out with the scope of this tool.
