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

[Laurent C.]

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

[GRASS-user] import .flt grid into grass

[Raphael.Viscarra-Rossel]

Hello,


A while back I posted a question about exporting .flt grids from grass. I
am still struggling with this, but now I have another question regarding
these files.  

I have 100¹s of these files (from a time series of data) that a colleague
produced for me in arcmap.  I have tried to import them into GRASS (as I
do not use or like arc ;-) but have not been able to do.

Any suggestions on how this might be possible? Or is it not?

I searched for answers on the web and list but I only came to some old
posts where the links to the conversations were no longer available.

Any ideas will be very welcome. Thank you.

Raphael.

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).

Please tell us what you used (r.in.gdal?) and which error came up and
which GRASS version you are using etc.
