[GRASS-user] Import point time-series as space-time dataset

GRASS GRASS user

Hello,

I'm working with files that represent the variation of a value over
time for a single point.
Looks like that:
0 1200
0.03125 1380
0.125 1500
0.3125 1620
0.65625 1740

I need to import them as a raster space-time dataset.
What I'm doing now is using a python script that does that for me.
Is there a way to do that with GRASS modules?

Regards,
Laurent

What exactly does you script do ?

Does that mean that each line represents one raster with one non-null pixel ? If yes, then I don't see much else then iterating over the file, using something like r.in.xyz to import each line as a raster and in parallel writing a text file with the map name and start time. This file can then be fed to t.register to register all the files into a space-time dataset. AFAIK, the temporal modules do not directly handle import & export of data (except for space-time datasets exported from GRASS).
