Dear Colleagues,
Many indexes are available in SNAP concerning vegetation, water and soil , However, I didn’t find the indices to identify the built up area, for instance
UI (Urban Index)
NDBI (Normalised Difference Built-Up Index)
IBI (Index-based BuiltUp Index)
NBI (New Built up Index)
I know that it is possible to use band math to calculate each one of the above indices, but the question is,
Which one of the above is most recommended using Sentinel 2 images?,
OR any other are not mentioned here, it is great pleasure if you refer to them!
references if that possible.
Many thanks for your contribution.
Dear Taha,
Thanks a lot for your kind answer,
Would you please to provide me with the link of the articles you found concerning the higher accuracy of IBI and NDBI!
With my best wishes,
You can use the dry built-up index (DBI) and dry bare-soil index (DBSI) as used by the following paper. You just have to use the corresponding band for the S-2.

Thanks a lot Sita Karki, for your very kind answer, I'll give try your suggestion
Dear @saravanan subbarayan thanks for your answer, but I'm looking for the best index, Not software.
