Hi Thomas,
The "out of the box"- option would be to use t.vect.observe.strds However, "r.what" is significantly faster, but requires with > 400 maps a little bit of scripting. My approach is this one (there you can find a little shell-script: https://www.mail-archive.com/[email protected]/msg38802.html (the "transpose" command i the script is nothing but a little awk-command, like e.g. here: http://stackoverflow.com/questions/13634816/using-awk-to-transpose-column-to-row) Hopefully there will e some development in that direction soon...

I have looked through the wiki: http://grasswiki.osgeo.org/wiki/Temporal_data_processing and saw the use of g.gui.tplot<http://grass.osgeo.org/grass71/manuals/g.gui.tplot.html> which worked for my small data set (see t.info<http://t.info/> output below) -- what I need, however, are the values and dates extracted by g.gui.tplot exported to a text file. How do I get these? I have looked through all the modules and can not find what I need.
