|
The GeoTIFF layer in this example calculates the Normalized Difference Vegetation Index (NDVI)
|
|
and Normalized Difference Water Index (NDWI) from two cloud-optimized Sentinel 2 GeoTIFFs: one
|
|
with 10 m resolution and red and a near infrared bands, and one with 60 m resolution and a short
|
|
wave infrared channel. The NDVI is shown as green, the NDWI as blue. The 4th band is the alpha
|
|
band, which gets added when a source has a `nodata` value configured.
