The ImageryTileLayer in this sample contains Landsat 8 imagery of the Glacier National Park.
When the application loads, the ImageryTileLayer will display the NDVI raster function result. Normalized Difference Vegetation Index (NDVI) is used to quantify vegetation greenness. It is useful in understanding vegetation density and assessing changes in vegetation health.
How it works
When the application loads, NDVI raster function is created. Then a Colormap function is created to display the result of the NDVI function. The colormap raster function is then applied to the ImageryTileLayer's rasterFunction property as shown below.
