Summary:<\/span><\/p>Normalized Differential Vegetation Index (NDVI) maps are produced by converting pixel values to NDVI = (Red \u2013 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.<\/span><\/p>Normalized Differential Water Index (NDWI) maps are produced by converting pixel values to NDWI = (green \u2013 NIR)/(green + NIR). Higher Planet scene numbers are layered over lower scene numbers. Normalized Difference Water Index (MNDWI) provides a different view of the Earth's surface combining different bands to make water bodies more obvious. This index can be used to identify flooded areas as well as heavily saturated areas.<\/span><\/p><\/p>
Suggested Use:<\/span><\/p>NDVI: NDVI is commonly used to distinguish healthy/active vegetation (1) from unhealthy/dormant vegetation (-1).<\/span><\/p>NDWI: Thresholding of NDVI is one technique used to distinguish surfaces covered by water (-1) from surfaces not covered by water (1).<\/span><\/p><\/p>
