Thanks for the tutorial. Simple, informative, nothing unnecessary.

[@geospatialschool]

You're welcome!

[@RosaBevington]

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

[@tvm73836]

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

[@RosaBevington]

@@tvm73836 I don't think people know about them or have the time/expertise to explore.

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?

[@geospatialschool]

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?

[@geospatialschool]

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

how to calculate NDVI from landsat collection 2 level 2 data?

[@wildlifeireland9514]

Awesome

[@geospatialschool]

Thanks!

[@angelicacanete9035]

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

[@geospatialschool]

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

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

[@geospatialschool]

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

How to find out the area of the higher NDVI and Low NDVI

[@geospatialschool]

You can symbolize based on different NDVI values
