[GRASS-user] tgrass: cumulative animation

[Martin Landa]

Hi,

I wonder how to easily create cumulative data layers animation. I have
raster time spatial dataset with few maps. Each map contains one value
(and NULL values). Pixels with non-data value do not overlaps in
strds.

I would like to create animation (ideally by g.gui.animation) showing
cumulative display. So:

1 frame shows first map
2 frame shows overlapped first and second map from strds
...

Is there any way how to create such animation without creating new strds?

And which tool could create such cumulative strds? I checked
t.rast.accumulate, but till now without success.

Thanks for any pointers, Ma
