This index can be used to identify flooded areas as well as heavily saturated areas.</div><div style='font-family:inherit; font-size:16px;'><br /></div><p><span style='font-weight:bold;'>Suggested Use:</span></p><p><span>The True Color RGB provides a product of how the surface would look to the naked eye from space. The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor. Some minor atmospheric corrections have occurred.</span></p><p><span>For 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.</span></p><p style='margin-top:0px; margin-bottom:1.5rem; font-family:"Avenir Next W01", "Avenir Next W00", "Avenir Next", Avenir, "Helvetica Neue", sans-serif; font-size:16px;'>For mNDWI, areas of existing water, such as a rivers or lakes appear in the darkest green with high values near 1, while dry land appears in the darkest brown with low values near -1. This product can be used to identify potentially flooded areas that can be seen in varying shades of green and light brown depending on the amount of moisture picked up by the satellite. Note: Areas of cloud cover will show up in varying shades of green/blue similar to water.<span style='font-family:inherit;'></span></p><div><br /></div><p><span style='font-weight:bold;'>Satellite/Sensor:</span></p><p><span>MultiSpectral Instrument (MSI) on European Space Agency's (ESA) Copernicus Sentinel-2A/2B satellites</span></p><p><span style='font-weight:bold;'>Resolution:</span></p><p><span>10 meters</span></p><p><span style='font-weight:bold;'>Credits:</span></p><p><span>NASA/MSFC, USGS, ESA Copernicus</span></p><p><span style='font-weight:bold;'>Esri REST Endpoint:</span></p><p><span>See URL section on right side of page</span></p><p><span style='font-weight:bold;'>WMS Endpoint:</span></p><p><a href='https://maps.disasters.nasa.gov/ags03/services/us_svrwx_202504/sentinel2_pah/MapServer/WMSServer' rel='nofollow ugc' target='_blank'>https://maps.disasters.nasa.gov/ags03/services/us_svrwx_202504/sentinel2_pah/MapServer/WMSServer</a></p><p><span style='font-weight:bold;'>Data Download:</span></p><p><a href='https://maps.disasters.nasa.gov/download/gis_products/event_specific/2025/us_svrwx_202504/sentinel2/' rel='nofollow ugc' target='_blank'>https://maps.disasters.nasa.gov/download/gis_products/event_specific/2025/us_svrwx_202504/sentinel2/</a></p></div> |
