Re: How to sample an STVDS based on an STRDS

Dear Ken,
there is no functionality for vector aggregation available in GRASS
GIS Temporal Framework. Dependent on your STVDS, maybe you can convert
it into a STRDS by using v.to.rast for each vector layer and then
organize the resulting raster layers in a new STRDS.

Best regards
Sören

I think I'm looking for the inverse of t.rast.aggregate.ds - that is, I have an STRDS with arbitrary intervals (roughly, 24 day windows moving about every 6 days). I have an STVDS with daily data. I'd like to aggregate the daily STVDS to match the STRDS.
