QGIS Remote Sensing - Calculate NDVI

[@SombreroBanana]

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

[@geospatialschool]

You're welcome!

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

[@tvm73827]

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]

@@tvm73827 I don't think people know about them or have the time/expertise to explore.

How could this be accomplished with multispectral tif files from a drone? Do just the NIF and R bands need to uploaded in QGIS?

[@jeetendrakumarpatel8585]

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.

[@geo15304]

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.

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.

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

[@feithecouchpotato]

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

Awesome
