VISIR® is a service providing optimized nautical routes in the Mediterranean Sea. The optimization regards total navigation time, taking into account safety of navigation.
VISIR® app can freely be used, after the registration at http://www.visir-nav.com.
The computation of the routes depends on model forecast of sea-state. The user can specify departure date and time, departure and arrival location, vessel type, and other parameters.
The routes are displayed on top of wave forecasts, superimposed on a map.
VISIR® is a product of the TESSA project, executed by:
Centro Euro-Mediterraneo sui Cambiamenti Climatici (CMCC). CMCC is responsible for the research activity, the distribution of ocean model products, the model behind VISIR®, and the realization of the User Interface;
Links s.p.a., which has realized the system for web publication of the route information and ocean forecasts.
Istituto per lAmbiente Marino e Costiero (CNR-IAMC).
For the submission of routes computation, the user must buy a subscription to the Visir service.
The available subscription is an in-app purchase with the following features:
- type: auto-renewable subscription

Without a valid subscription, the user can freely navigate the app, visualize 5 pre-computed routes and explore all the information about the geodetic and optimal routes but cannot submit his own routes computation.
