Nautical charts and nautical publications - Wärtsilä

Environmental overlay: Visual (and object-attribute based) representation of MARPOL-designated areas, such as Emission Control Areas (ECAs) and Special Areas. Helps with environmental compliance and voyage planning. Advanced Intelligent Routing (AIR): Used together with Navi-Planner, for example, AIR provides automatic generation of port-to-port routes, including complex multi-stop voyages. AIR accounts for vessel parameters, chartered depths, and traffic schemes can dramatically speed up the voyage planning process. Ports database: A comprehensive, structured global port database containing terminal information, pilotage and berth details. Ideal for streamlining route planning, port calls and ETA prediction models. Piracy overlay: Regularly updated zones with incident alerts and threat level visualisation. Bathymetric data overlays: For example, Draft Information System (DIS) for St. Lawrence seaway, provided detailed seabed information to support safe navigation in shallow and complex waters. Weather services: Real-time and forecast meteorological data which supports strategic voyage planning as well as choosing optimal routes while sailing.
