Google Earth Engine Burnt Area Map (GEEBAM)

PLEASE NOTE:

GEEBAM is an interim product and there is no ground truthing or assessment of accuracy. Fire Extent and Severity Mapping (FESM) data should be used for accurate information on fire severity and loss of biomass in relation to bushfires.

The intention of this dataset was to provide a rapid assessment of fire impact.

In collaboration with the University of NSW, the NSW Department of Planning Infrastructure and Environment (DPIE) Remote Sensing and Landscape Science team has developed a rapid mapping approach to find out where wildfires in NSW have affected vegetation. We call it the Google Earth Engine Burnt Area Map (GEEBAM) and it relies on Sentinel 2 satellite imagery. The product output is a TIFF image with a resolution of 15m. Burnt Area Classes:

1. Little change observed between pre and post fire

2. Canopy unburnt - A green canopy within the fire ground that may act as refugia for native fauna, may be affected by fire

3. Canopy partially affected - A mix of burnt and unburnt canopy vegetation

4. Canopy fully affected -The canopy and understorey are most likely burnt

Using GEEBAM at a local scale requires visual interpretation with reference to satellite imagery. This will ensure the best results for each fire or vegetation class.

Important Note: GEEBAM is an interim product and there is no ground truthing or assessment of accuracy. It is updated fortnightly.
