NDVI over Cape Coral & Fort Myers a month prior to Hurricane Ian.

## NDVI & Entropy Analysis

Figure 3 depicts the Normalized Difference Vegetation Index (NDVI) around Cape Coral a month prior to Hurricane Ian. NDVI serves as a fundamental metric for comprehending the vitality and abundance of vegetation within a specific geographical region. In this data story, we obtained NDVI data from Harmonized Landsat Sentinel-2 (HLS) that is aboard the NASA/USGS Landsat 8 and 9 satellites over two different days encompassing the area prior to the hurricane and post-hurricane. The primary vegetation in this portion of Florida can include grasslands and forested regions. In Figure 5, the darker green locations show a relatively high abundance of vegetation in a particular location. The light green or yellow locations depict areas with low vegetation meaning that these areas are likely urbanized in a location such as this. Notice Pine and Sanibel Islands just east of Cape Coral. These areas were particularly hard hit by Ian. Storm surge inundated much of the access points to the islands along with washing away much of the vegetation in these locations.

Figure 4: NDVI over Cape Coral & Fort Myers a month after Hurricane Ian.

</Figure>
<Prose>
Figure 4 shows a significant change in the vegetation landscape post-Hurricane. Note that we mentioned Pine and Sanibel Islands. Much of the vegetation seems to have been washed away by the storm surge. Punta Russa, located on the southwestern tip of Fort Myers beach along Sanibel Causeway, is another location that experienced catastrophic storm surge during Ian. Note the change in NDVI at the tip of Punta Russa. In addition to statistical analyses, the notable transformation of vegetation in these dispersed areas holds significant scientific importance, as it provides compelling evidence of the formidable impact exerted by this catastrophic hurricane.
