Hi, This is interesting. Basically the end result is a multi band raster, which can also be done by stacking multiple band rasters. I don’t know anything about this v.vol.rst algorithm but it sound interesting. I do do see a problem though. Your data sets may not all like to be interpolated with a single algorithm. So unless you can modify the interpolation algorithm for each band, you will probably end up with a bad raster data set. The chosen algorithm must work like the phenomenon you are trying to study.
As an example, using a simple TIN to predict the weather will most likely fail as weather pattern don’t work like a TIN. Inverse distance weight would probably be better.
