So, for that, I have to do layer stacking and classification or direct NDVI in ArcGIS will work. Could you please illustrate the steps and how to start with the work?

However, usually, strict NDVI values aren’t declared. It is true that NDVI values range from -1 to 1 but in strict form the intervals aren’t given. So, that creates the problem to reclassify the NDVI values and impossible to estimate the area coverage and the like of the vegetation cover. Could you please help us with the clear values (ranges) of the computed NDVI to estimate to generate more results?

Could you please suggest any tutorials?

Regards

Can somebody guide me how to do this with NDVI?

1. You have to select the two bands that you want to run the NDVI on.
2. Image analyst extension isn’t turned on.

Try those two. Let me know if you have any luck

Is there any way for you to go in the field and ground truth your results? That is the only way to be certain.

For example, the vegetation in the past recorded low when LULC change analysis justify high percentage as regards to vegetation.

Cheers!

You’ll need finer spatial and spectral resolution data such as LiDAR, hyper/multispectral
