We explore how to identify burned areas and assess burn severity by comparing pre-fire and post-fire NBR values, as well as calculating the dNBR to evaluate vegetative regrowth over five years. I demonstrate the steps in FME Workbench, including setting up readers, performing raster calculations, and exporting results to GeoTIFF and CSV formats. Please make sure to download the source data from the article's download section before getting started. If you have any questions, feel free to reach out through a support ticket or the FME community."}
