The map suggest a Storm Arwen windblown area across GB of around 5500ha but it is assumed this is an underestimate.
A Citizen Science App has been developed to enable and encourage feedback on the map. Windblow Assessment (arcgis.com). Feedback will improve the map data and improve the algorithm that processes the satellite data to improve the method for future storms.
The App is very easy to use with simple questions to enable feedback. Area corrections can be made and photos added. When areas are validated the colour code of the map changes from pink to blue. 15% of sites have been validated so far. The public forests will work with Forest Research to add their validation. A review of the data will be made after 23rd January but it is expected validation can continue thereafter.
