Comparison of NDVI before and after 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.
