When using the collocation tool to compare two NDVI images it returns this expression: Undefined symbol ‘ndvi_flags_M.NDVI_ARITHMETIC_M’
Could anybody help with this error?

Hi @Abigail_Danks,
Welcome to the forum!
Could you confirm me your pipeline?
It should look like:
Product1 => NDVI \\
Collocation
Product2 => NDVI //
Is it right? could you give me the names of two products you are using so I can try myself?
Cheers,
Martino
I get the same error message but only after I try a band maths operation after colocating (successfully) an NDVI and a SAVI processing from a single S2 MSI image. I can colocate two supervised classification files and undertake a band math operation fine - and band maths works with bands inside the MSI image - but it doesn’t work with the NDVI/SAVI images… Michael Hewson
you can use the stack tool as an alternative as described here: Band Math Expression Error in Collocate
Many thanks - yes that works MH
