This grasshopper definition is designed for urban planners and landscape architects when designing/renovating a city's waterfront. It is constructive at the initial stage of design, when a site is undecided, or when a rough site is chosen, and the site's zoning is to be decided. It shows the existing waterfront condition as well as the condition when new planned waterfront sites are implemented.

What you need:

• Install Grasshopper in Rhino 6 or 7 for either windows or mac.
• Install 'Caribou' (must) & 'Human' (maybe) to allow the definition to work correctly.
• Download OpenStreetMap data.

Sample map:

1. A customized layer of Area of Interest - define your regions and values (those components are shown in black).
2. A base layer - coastline & major railways & waterways.
3. A zoning layer - Private; Commercial; Open public; Industrial.
4. A waterfront access point layer - access points that connect the sea with the inland area, e.g. piers, ports and terminals.
5. A legend that shows the different colours and the percentage made up of the zones.
