#3932: i.vi: NDWI unnecessarily requires red band
---------------------+---------------------------------
Reporter: sbl | Owner: grass-dev@…
Type: defect | Status: new
Priority: normal | Milestone: 7.8.1
Component: Imagery | Version: git-releasebranch78
Keywords: i.vi | CPU: All
Platform: All |
---------------------+---------------------------------
i.vi requires a red band in any case, even if e.g. NDWI does not need one.
So, in order to make the module run, a map has to be given also for the
red band. That seems like unexpected behavior to me.
Maybe better to leave all input bands optional and add a check for the
requested VI if required bands are provided...
