Remote Sensing Filters

I have a eos 1000 with ef 35-70a lens.
I am interested in
finding underground structures , tombs - i m an archeologist - on the plains
finding thorium , uranium
vineyard health and following the growth
I read many interesting articles specialized to my problems but they use digital spectrometers.
Lumicon produces many astronomy related narrow band filters for space.
Where can I find remote sensing filters or gels for earth photography ?
I think someone might produce them.

Do you have any photos you can share with us?

I don't think you could expect to just use a filter and get good results. Look at this article on Spectrometers on Wikipedia. A lot of it appears to be in the optical system more than the recording medium. Spectrometers are used on space telescopes.
