<p>Hi Thomas,</p>
<p><br>
</p>
<p>The "out of the box"- option would be to use</p>
t.vect.observe.strds
<p>However, "r.what" is significantly faster, but requires with > 400 maps a little bit of scripting.</p>
<p><br>
</p>
<p>My approach is this one (there you can find a little shell-script: <br>
</p>
<p><a href="https://www.mail-archive.com/grass-dev@lists.osgeo.org/msg38802.html">https://www.mail-archive.com/grass-dev@lists.osgeo.org/msg38802.html</a></p>
<p><br>
</p>
<p>(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)<br>
</p>
<p><br>
</p>
<p>Hopefully there will e some development in that direction soon...</p>

<p>Cheers</p>

I am just getting started using GRASS raster temporal data analysis capabilities (both GRASS 7.0 and 7.1svn as of this AM) -- pretty cool, with some nice features. I have looked through the wiki:<br>
<br>
<a href="http://grasswiki.osgeo.org/wiki/Temporal_data_processing">http://grasswiki.osgeo.org/wiki/Temporal_data_processing</a><br clear="all">
<div>
<div><br>
</div>
<div>and saw the use of <a href="http://grass.osgeo.org/grass71/manuals/g.gui.tplot.html" rel="nofollow">
g.gui.tplot</a> which worked for my small data set (see <a href="http://t.info/">
t.info</a> 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.<br>
