Using just one ID to start with (with 80 timestamps) I've created 80 vectors, each with their own layer and v.timestamp. I can then patch these together to one product with multiple layers.

If I t.register all of these, I also see what I expect to see with g.gui.timeline. If I run "g.gui.animation stvds=t" it reports "Topology [...] is invalid".

Is there a way to export STVDs and see the time component in QGIS or KMZ/Google Earth?

Thanks,

  -k.
