IMAGINE Discussions

Dear all,

I am processing a data with the Spectral Analysis workstation and I would like to understand how the tools manages no data.

I have this hyperspectral images, that has 0 as NODATA.

I have some pixels, inside the image, that have 0 as value:

In Spectral Analysys workstation the signature is like this:

So the signature goes to 0 when the pixel has 0 (NO DATA).
Is not possible to ignore that value?

I don't want that the signature goes to 0 values.

Thanks!

Hi gmaldera,

Spectral Analysis Workstation was written before NODATA recognition was added to IMAGINE. Unfortunately there is no way currently for Spectral Analysis Workstation to ignore NODATA values.
