description: The Experimental Binary NDVI change product is highlighting areas that experienced change (of any kind) since the pre-event Copernicus Sentinel-2 pass (22 September 2024) used in the analysis. The product is further filters to reduce noise and focus the identification on the more pronounced areas of change in an effort to identify areas that may have experienced damage during Hurricane Helene's passage and associated water and wind impacts. Usage: This binary mask layer is designed to overlaid with post event imagery (pre if it is available as well). The True color imagery or the Color IR RGB should be used to orient the user to areas that match the type of change being investigated. Color IR RGB uses infrared channels to isolate areas of high vegetation (and greenness) in red from areas that are not, such as cities, rivers, which will appear in shades of green/teal. Clouds are white while cloud shadows tend to be black (or close to it) Caveats: The include cloud mask is not capturing all of the clouds and is causing some areas to be falsely identified as change in the product. This is why it is recommended to use the product with the True Color and Color Infrared RGB. Some areas of open water were flagged as change and this is most likely due to changes of sediment and debris in these open water areas. Many areas of changed were flagged within areas of rugged terrain. Some of these area are actual changed as result of damaging winds and water. Others may be related to clouds and cloud shadows. Using the this product with the RGB imagery should be help support interpretation.
