Modified normalized water difference index (mNDWI) composite processed from Landsat 8 OLI data. This composite was created from 16 images of the southern cusp of Cape Hatteras National Seashore captured between February 2023 and February 2024. The yellow-orange shapes represent barrier islands, surrounded by shades of blue that indicate water. Processing images by calculating mNDWI is useful in delineating shoreline change over time.

Composite land cover image of the Salinas River Watershed in California, calculated using Landsat 8 OLI and Landsat 9 OLI-2 imagery from November 2022 and November 2023. Red/pink shades indicate developed areas, green shades denote forests, and dark brown/yellow shades signify croplands/grasslands. These characteristics affect surface infiltration capacity and influence overall flood risk.

NDVI-processed imagery from Landsat 8 OLI data. This composite image of the Bridger-Teton National Forest and surrounding areas was taken over the Summer of 2023. Shades of yellow and light green indicate health vegetated land surface, while darker blue areas show water and alpine ridges. Areas of lower NDVI are prone to higher fire risk and are therefore of interest to pre-fire management practices.
