Hermits Peak Fire, HLS (2022)

This Harmonized Landsat Sentinel-2 (HLS) data animation shows the development of the Hermits Peak Fire which began on April 6, 2022, in the U.S. Forest Service Santa Fe National Forest. This video shows the fire as it spreads across the landscape from April 4, 2022, to August 2, 2022. The three views in the video demonstrate different methods of visualizing where the fire has burned using satellite imagery. The left image emphasizes fire hotspots as bright red-orange and burned areas in red using shortwave infrared (SWIR), near infrared (NIR), and red bands. The middle image uses Normalized Difference Vegetation Index (NDVI) values calculated using NIR and red bands to highlight vegetation health and where fire damage to vegetation occurred. Finally, the right image uses the NIR, red, and green bands to emphasize healthy, dense vegetation in red and areas where the fire has burned in black.
