Another approach to visualizing the results of meteorological and oceanographic numerical models on the web - using a relational database and client-side visualization

The ability to interactively display and analyze the results of the AdriSC forecast model - as well as real-time measurements at various locations along the Croatian coast - was seen as critical to the development of a meteotsunami early warning system, and together a dedicated web interface for the model was created (http://www.izor.hr/adrisc).In contrast to existing solutions that rely on prefabricated georeferenced representations, we decided to use a relational database and client-side visualization based on previous experience in spatio-temporal data visualization. Such a solution reduces the amount of transferred data, as only numerical values are transferred and no prepared image visualizations are required. This alone allows an unlimited number of customizations in the visualization. The Oracle database 19.2, Standard Edition, and ORDS under the Tomcat Application Server were used.The use of this type of visualization offers new possibilities such as interactivity and a shorter data loading time. The use of a relational database in the context of model visualization is not a common practice, although numerical models generate very large amounts of data. The relational database offers some new possibilities in terms of visualization and comparison of model results with real measurements.
