What is a Route Network & Routing Service?

Route Network API 1

  • Our routing service is based on a worldwide network of ports, waypoints and leg lines – referred to as the Route Network.
  • The aim of the routing service is to provide a fully automated route plan, adjusted for specific vessel parameters; the plan factors-in nautical information, administrative and environmental restrictions affecting navigation, the latest Notices to Mariners, and warnings.
  • The routing service could be delivered to Solution Partners as a Route Network Database or as automatically calculated routes delivered via the Route Network API.
  • The Route Network has been combined with the route-calculation algorithm that uses additional data, such as gridded depth information, No-Go Areas , and restricted areas. This enables the safest possible navigable route to be calculated between any geographical locations in the world.

Why Integrate our Route Network and Routing Service?

  • Our team of navigational experts (Master Mariners) uses various sources for extending and updating the Route Network. . Embedded into the Route Network, the final data structure and the attributes, sourced from nautical charts, sailing directions and local routing regulations, can handle even complex routing scenarios.

  • The Route Network is constantly updated with supporting metadata; this is done to allow for computerised route-finding by algorithms that have all necessary and relevant information available to calculate the best route that is safe, appropriate and efficient.

RNW API Key Functions

  • Calculation of shortest safe route via API Calls or RNW Server Web user interface

  • Route calculation, taking into account vessel parameters such as length, beam, static draft, safety margins, vessel type and cargo type.

  • Configuring and adjusting voyage parameters, e.g., defining the port of departure/destination, points and areas to be avoided or passed through.
  • The RNW Server API response, containing the route file in RTZ format, always includes a set of waypoints and schedule.
  • The route file includes information required for  creating a voyage plan compliant with requirements, such as voyage segments, XTD, safety route check, points of interest, and restrictions along the route.

Route Network API 2

  • Option to add weather routing to the RNW API Calls.  The route calculated with the Weather Routing API will include information about the weather forecast, and vessel performance for the voyage (fuel consumption, cost, CO2 emission, predicted CII rating).
