<div>The years before it was always available on OSGeo server: <a href="http://download.osgeo.org/pgrouting/foss4g2010/" target="_blank">http://download.osgeo.org/pgrouting/foss4g2010/</a></div>
<div>
It seems I forgot to place the 2011 workshop there as well. </div>
<div><br>
</div>
<div>The workshop documentation source is on Github: <a href="https://github.com/pgRouting/workshop" target="_blank">https://github.com/pgRouting/workshop</a></div>
<div>So all you're missing is the sample data. But you can
download any OSM data or even use the sample data of 2010.</div>
<div><br>
</div>
<div>In case you're using Ubuntu/Debian you can install last years
workshop as a package easily:</div>
<div><a href="https://launchpad.net/%7Egeorepublic/+archive/pgrouting/+packages" target="_blank">https://launchpad.net/~georepublic/+archive/pgrouting/+packages</a></div>
<div>It contains the sample data of Denver as well. Or you
download the tarball [1] and extract it. </div>
<div><br>
</div>
<div>Or, you use OSGeo Live DVD. It contains the workshop as well:</div>
<div><a href="http://live.osgeo.org/en/quickstart/pgrouting_quickstart.html" target="_blank">http://live.osgeo.org/en/quickstart/pgrouting_quickstart.html</a> (see
"What's next" at the end of the page).</div>
<div><br>
</div>
<div>Hope that helps,</div>
<div>Daniel</div>
