 The dynamically generated Reflectance (Bands 8-4-3, False Color) imagery layer is a false color composite that is used to gauge plant health and assess plant density. Plants reflect in near infrared and green light, while absorbing in red. reas with better vegetation health appear red, and denser plant growth is a darker red. Cities, urban areas, and exposed ground appear grey or tan and water is blue or black.

 The image is applied with a divergent blue-green to brown color palette. It depicts areas with a lot of green leaf growth, indicating the presence of chlorophyll, in dark green colors.
