The True Color RGB is produced using the 3 visible wavelength bands (red, green, and blue) from the respective sensor.

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><span style='font-weight:bold;'>Satellite/Sensor:</span></p><p><span>Landsat 9 Operational Land Imager (OLI), Landsat 8</span></p><p><span style='font-weight:bold;'>Resolution:</span></p><p><span>30 meters</span></p><p><span style='font-weight:bold;'>Credits:</span></p><p><span>NASA/MSFC, USGS</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/landsat/MapServer/WMSServer' rel='nofollow ugc' target='_blank'>https://maps.disasters.nasa.gov/ags03/services/us_svrwx_202504/landsat/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/landsat/' rel='nofollow ugc' target='_blank'>https://maps.disasters.nasa.gov/download/gis_products/event_specific/2025/us_svrwx_202504/landsat/</a></p></div> |
