initially get an error:<br>
<br>
ERROR: relation "vertices_tmp" does not exist<br>

I think Daniel will have to answer this. pgr_fromatob() must be a wrapper as that is part of the tutorial because it is not part of the pgrouting release.<div class="im"><br></div></blockquote><div><br></div><div>This is the function: <a href="http://workshop.pgrouting.org/chapters/wrapper.html#route-between-lat-lon-points-and-return-ordered-geometry-with-heading">http://workshop.pgrouting.org/chapters/wrapper.html#route-between-lat-lon-points-and-return-ordered-geometry-with-heading</a></div>

It should be all explained. If you're missing some information, or something is unclear, then feel free to ask.</div>
