Re: [GRASS-dev] sample vector temporal data

Hi devs, In r63363 I submitted an update of space time doc for several modules using the new temporal dataset. I'm going to make the new dataset available in the next days to test and comment it. Stay tuned ;-) -- ciao Luca http://gis.cri.fmach.it/delucchi/ www.lucadelu.org

Anna, to put these data into context, the dataset should include also at least one ortho (probably for 2009) and perhaps also a lidar-based DEM for 2009. I think that the detail will work better - maybe you can show it on orthophoto or a DEM to make it easier to understand what the lines mean.
