But why not include values from the adjacent water bodies to calculate the average vegetation around us? Thanks.

It’s good for detecting vegetation. But it might not be so good at determining something like soil moisture content, which could be better with synthetic aperture radar. There are a lot of different examples you can come up with.

Hi Alvin. I personally don’t think it is possible. Would the criteria be a higher NDVI is equal to higher elevation? That’s the equivalent of saying more green means more height. There may be a tiny correlation between the two, but I have my doubts for a strong relationship or any at all.

Thinking if I can combine the NDVI with the CHM to produce a somewhat reliable DTM. I’m looking for DTM for exploration purposes.
