Skysat collects 4-band imagery which allows for multiple derived products to be produced.</span></p><p>Normalized Differential Vegetation Index (NDVI) maps are produced by converting pixel values to NDVI = (Red – NIR)/(Red + NIR), NIR indicates the near infrared band. The dynamically generated Normalized Difference Vegetation Index (NDVI) layer is an index for quantifying green vegetation. It reflects the state of vegetation health based on how vegetation reflects light at certain wavelengths.</p><p><span style='font-weight:bold;'>Suggested Use:</span></p><p>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.</p><p><span style='font-weight:bold;'>Resolution</span></p><p><span>~1 m</span></p><p><span style='font-weight:bold;'>Credits</span></p><p><span>NASA Disasters Program, Processing from MSFC, Planet.
