Wow!! My mind is blown! So much more adaptable than Pix4D!

Absolutely! I don’t know why people pay so much money for pix4d. I guess they are too lazy to explore open source options!!

Great, I have a query regarding how to deal with multiple imageries? As I have to use 6 Landsat imageries for same analysis and further need to clip it by a mask layer. please explain.

Thank you so much for the tutorial! It's very informative and easy to follow. Do you know how to export the NDVI scores of a certain area after getting the layer image?

If you want average NDVI you can use zonal stats. If you just want to extract the raster for a specific area, then you can use extraction tools.

Thank you for this instructional video. Kindly is there need to do radiometric corrections and surface reflectances before calculating the NDVI?

It depends which data you are using. If you are using Landsat ARD (analysis ready data) then you do not need to perform corrections.

Hi, is there a tutorial similar to this procedure but translated into a PyQGIS programming code rather than the GUI?

Yes, you can search for my video on using the qgis raster calculator with PyQGIS

Can't find the changing color option inside symbology :(

Did you change the symbology type from singleband gray to singleband pseudocolor?

You can symbolize based on different NDVI values
