<div dir="ltr"><div>Hi all,<br><br></div><div>here is my report for the last week<span style="font-weight:normal"><font><span><font>.</font></span></font></span><font> I<font> continued the implementation </font>of the temporal algebra. In detail, I created functions to </font>compare space time datasets by their topology and to perform temporal selection on raster and vector datasets, respectively. The temporal selection of space time datasets can be performed with the module t.select, which can be found in my repository. I will update my wiki page with documentation and examples for this new module soon. We also reconsidered and changed some functionalities in the temporal algebra concept. Take a look in the GRASS trac wiki:<br>
