Developing a GIS Framework for Effective Weather Routing in the Tyrrhenian Sea

Weather routing is a navigation technique that uses real-time meteorological and forecast data to chart the safest and most efficient course for maritime vessels, minimizing the risks posed by adverse weather and sea conditions. It involves the integration of spatial analysis techniques to optimize the route. Spatial analysis operations, like processing and visualizing geospatial data, can be carried out within a Geographic Information System (GIS). In this study, a GIS framework for weather routing is developed, utilizing datasets for the Tyrrhenian Sea provided by the Weather and Sea-State Monitoring and Observing System at Parthenope University of Naples, including wave direction and height. Methodologically, the study involves the creation of thematic maps using raster calculators to classify and visualize the aforementioned meteorological and marine variables. Within this context, a navigational framework is developed in QGIS, integrating raster data as well as vector data to provide navigators with advanced decision-making support. Preliminary findings suggest promising enhancements in navigation capabilities, indicating significant potential for improving route efficiency and safety through the application of advanced GIS-based weather routing techniques.
