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

[Ken Mankoff]

Hi,

I'm fairly new to the temporal features in GRASS. 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.

I can do this using t.sample, parse that, and aggregate. But this seems to be a fair amount of manual work, and it looks like GRASS abstracts much of this if I were going the other way - subsetting a STRDS based on an STVDS.

Is there a simple way to do this in GRASS - i.e. Is there a command I'm missing or mis-understanding? Or does subsetting vectors take more work because there is no analog to t.rast.aggregate.ds?

Thanks,

  -k.
