Enhanced GIS widget

Users often wrongly convert latitude and longitude coordinates which leads to the selection of a wrong area. This is highly inefficient for ECMWF as a data provider, as the same data request has to be processed multiple times. 

The challenge was aimed at developing a widget that selects and displays areas on a map. Such a widget will be useful for many web applications across ECMWF. The widget is based on Leaflet (a javascript library for interactive maps) and provides different tools, e.g. drawing and searching. The widget also offers a grid point system resembling ECMWF’s model grid points.
