--- layout: example.html 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. tags: "cog, ndvi" ---
