Downloading LANDSAT satellite imagery bands (band 4 and band 5 respectively RED and NIR earth surface reflectance) - see also online material https://www.cirgeo.unipd.it/didattica/GIS/01x_access_geodata.html#USGS:_EarthExplorer
04:24 - level 1 and level 2 imagery processing level difference (see also Part 1 video)
04:56 - mission start and end of life date
10:00 - match band name with wavelength to download RED and NIR needed for calculating NDVI (https://www.indexdatabase.de/db/i-single.php?id=58)
10:36 - save QGIS project + data all in same folder for easy access using the browser panel in QGIS
10:45 - download Band 4 and Band 5 from Landsat 9 imagery using USGS Earth Explorer website
14:35 - grey scale color style to raster
18:20 - raster calculator from processing toolbox
22:40 - styling with colors the NDVI raster
24:20 - frequency histogram distribution of pixel values to assess the min and max values for stretching the color scale
28:50 - using cumulative count cut method to define min and max range for a good contrast color scale
