Australia's Bureau of Meteorology has developed a map to visualize storage, allocations, and trading information for catchments in the Murray-Darling Basin using Mapbox and ESRI technologies. This project, built with React, employs the react-map-gl component from the vis.gl framework, allowing integration with existing ESRI tilesets. The map is crucial for the Basin, which supports over 2.2 million people, including 40 First Nations communities, and is home to significant wetlands and species. Mapbox's customizability and integration capabilities allowed the Bureau to efficiently design and launch a public portal, aiming to enhance productivity and provide critical information about the region that produces 40% of Australia's agricultural output.
