i.vi only produces 0 value maps

Description

i.vi is only producing 0 value maps. I suspect that it is because it is using integer calculations for values that should be floating point.

This is still a problem for the following image products: ARVI, EVI, GARI, GEMI, and MSAVI. I could not test MSAVI2 because I did not have requisite soil data.

Yann has committed a fix in r53063 for GARI and a missing free memory (NIRchan) condition.

Milestone: 7.0.07.0.3
Resolution: fixed
Status: newclosed

I have added working examples in r67425 (and r67426).

i.vi produces output, it is needed to use reflectance values as per manual.

Closing.
