Brief description

EFAS is part of the prestigious European Centre for Medium-Range Weather Forecasts (ECMWF).
The European Flood Awareness System (EFAS), provides overviews on ongoing and forecasted floods in Europe with up to 10 days advance notice.
The current EFAS system provides its stakeholders twice-daily early probabilistic flood forecasts of the highest quality through a web portal. Its aim is to provide useful, complementary, and shared information on upcoming floods to regional and national hydrological institutes whose responsibility is to communicate flood warning globally.

Our role

We developed the new MapViewer Web Application of the new web portal of the European Flood Awareness System (EFAS) (
The MapViewer is made up of an advanced Map Viewer that allows different types of users to analyse geographical data supporting the whole management cycle for floods.
The Map Viewer, allows navigation, provides a set of Data Tools allowing the user to search across multiple datasets or within a single dataset and compare different datasets, animate the map series etc.
The Web Application contains a section dedicated to displaying the  maps (E-MV) that provides live maps to support navigation and user queries.
The viewer will be at the heart of the application allowing the user to display data and allow the Forecaster on duty to perform the analysis.
It was developed with an eye to address the user needs, hence considerable effort went into the the user interface and user experience and offers a modern User Interface which is fast, interoperable and optimized for both fixed and mobile devices (smartphone / tablet).
