📌 This video shows how to:
open Landsat8/9 and Sentinel 2 Satellite Imagery in ArcGIS Pro
load bands with Color IR in Landsat and Sentinel
combine bands with Composite Bands tool
calculate NDVI with Raster Functions (NDVI and Band Arithmetic)
calculate NDVI with Raster Calculator
📌 Please don't forget that Raster Functions do not save the output on a file, so you have to save it to your project directory with Export Raster tool.
📌 Most used indices are:
Vegetation Index: NDVI = (NIR - Red) / (NIR + Red)
Water Index: NDWI = (Green - NIR) / (Green + NIR)
In Landsat 8/9:
NIR = Band5
Red = Band4
Green = Band3
In Sentinel 2:
NIR = Band8
Red = Band4
Green = Band3
