It reflects the state of vegetation health based on how vegetation reflects light at certain wavelengths.Suggested Use:NDVI: Dark green colors are areas with a lot of green leaf growth which indicates the presence of chlorophyll. Chlorophyll reflects more infrared light and less visible light. Areas with some green leaf growth are in light greens, and areas with little to no vegetation growth are even lighter greens.Satellite/Sensor:Landsat 9 Operational Land Imager (OLI)Resolution:30 metersCredits:NASA/MSFC, USGSEsri REST Endpoint:See URL section on right side of pageWMS Endpoint:https://gis.earthdata.nasa.gov/gis05/services/DISASTERS_EX2601_201809_HURRICANE_FLORENCE/ex2601_landsat_ndwi/ImageServer/WMSServer</div></div></div> NASA/MSFC, USGS <div style='text-align:Left;'><div>NASA data and products are freely available to federal, state, public, non-profit and commercial users.
