title: NDVI from a Sentinel 2 COG

shortdesc: Calculating NDVI and applying a custom color map.
|
|
docs: >
|
|
The GeoTIFF layer in this example draws from two Sentinel 2 sources: a red band and a near-infrared band.
|
|
The layer style includes a `color` expression that calculates the Normalized Difference Vegetation Index (NDVI)
|
|
from values in the two bands. The `interpolate` expression is used to map NDVI values to colors.
|
|
The `layer.getData()` method can be used to retrieve pixel values from the GeoTIFF. Move your mouse
|
|
or tap on the map to see calculated NDVI values based on the red and near-infrared pixel values.
