Interactive map to visualize and crowdsource flood related information using OpenStreetMap and Mapbox GL JS
If your street, building or neighborhood name is missing on the map, you can add it to the basemap directly by editing OpenStreetMap. The flood map will be updated with the new street in under 10 minutes.
The flooded streets layer is contributed by the public. Contributions are anonymous with no version control for the sake of simplicity.
You are encouraged to make use of the collected data for further analysis. Download the latest flooded streets layer as a geojson using this Ajax request.
