Think of it like a parking lot map, but for ships.\n\n---\n\n### Key Elements of a Berth Map\n\nA typical berth map will include:\n\n- **Berth locations**: Numbered or named docks/slips where vessels are moored.  \n- **Wharves or piers**: The structures extending into the water that allow access to vessels.  \n- **Depths / Water levels**: Required to know which vessels can safely dock where.  \n- **Terminal buildings / access points**: Where passengers or cargo are loaded and unloaded.  \n- **Container yards, storage areas, truck lanes**: For cargo ports.  \n- **Labels or identifiers**: Terminal numbers, berth numbers, sometimes the length and depth of each berth.  \n\n---\n\n### Types & Uses of Berth Maps\n\n- **Cargo Terminals**: Show where container/crane facilities are, capacity, shipping lanes.  \n- **Cruise Ports or Ferries**: Highlight where each vessel docks relative to terminals.  \n- **Marinas**: Show slips where boats are stored or overnighted.  \n- **Ship Scheduling / Optimization**: Used in planning which ship gets which berth when (known in operations research as berth allocation). ([en.wikipedia.org](https://en.wikipedia.org/wiki/Berth_allocation_problem?utm_source=openai))\n\n---\n\n### Examples\n\nSome real-world berth maps include:\n\n- Port of Long Beach / Port of Los Angeles berth & terminal maps with berth numbering, wharf lengths, and facility layout. ([sfkcorp.com](https://sfkcorp.com/resources/port-maps/?utm_source=openai))  \n- Yusen Terminals\u2019 \u201cTerminal Maps\u201d showing berth ranges (e.g., \u201cBerth 212-223\u201d) with associated access and yard layout. ([yti.com](https://yti.com/terminal-maps/?utm_source=openai))  \n- Ferry terminals including maps with numbered berths (e.g., \u201cBerth 3\u201d) and terminal layout for passenger access. ([bcferries.com](https://www.bcferries.com/web_image/h5f/h62/9044527054878.pdf?utm_source=openai))  \n\n---\n\nIf you like, I can pull up actual images of berth maps for a specific port or context (cargo, cruise, marina) so you can see what they look like."
