Service Description: Sample NDVI data showing damaged canopy during Winter Storm Mara (2023) according to the Texas A&M Forest Service. Sample is for Hancock neighborhood only.
An analysis of satellite imagery supported and refined estimation of the extent and severity of damage. Sentinel-2 imagery was collected immediately before (Jan. 26) and after (Feb. 5) the ice storm. Comparing the Normalized Differenced Vegetation Index from these two scenes over Austin resulted in an estimation of canopy damage including four categories:
(1) No damage (NDVI change greater than -0.05);
(2) Light damage or stress (NDVI change -0.05 to -0.1);
(3) Moderate damage (NDVI change -0.1 to -0.15);
(4) Heavy damage (NDVI change less than -0.15).
