Maybe your start point is in a trap due to a barrier or similar?<br>

<div>Hi all,</div>
<div>no answer, but I’ve found these two setting in
config.properties, which I changed as follows:</div>
<div><br>
</div>
<div>
<div style="margin: 0px; font-size: 11px; font-family: Menlo;">index.highResolution=1000</div>
<div style="margin: 0px; font-size: 11px; font-family: Menlo;">index.maxRegionSearch=8</div>
</div>
<div><br>
</div>
<div>But it doesn’t seem to help. First question is, do I need to
recompile after changing these two variables ? do I need to
rebuild the graph ? well, I did both anyway, but it still
sometimes returns « point 0 not found » when the coordinates is
more than around 300-500m from the nearest road. Do I need to
change something else ?</div>
<div><br>
</div>
<div>Thanks,</div>

I’m trying to find which option controls the max distance
taken in account when looking up the closest edge for the
start and end point given in a search. In some areas that are
very poorly mapped, it’s sometimes possible to give a
coordinate that is too far away from the closest road and the
server returns an error. I’d like to increase this value.<br>
<br>
Thanks,<br>
