[GRASS-user] How to sample an STVDS based on an STRDS

[Sören Gebbert]

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.
