No :)<br>
as you already figured out. minNetworkSize specifies the number of
nodes to recognize it as a standalone island. If you increase the
default value bigger islands will be removed.<br>

Well ... it is a simple solution for one-vehicle-graphs. There are
more complex solution still on our todo list<br>

<br>
yes, real islands should not be removed :)<br>

<div>OK, I’m a happy camper. <span style="font-family: Menlo;
font-size: 11px;">prepare.minOnewayNetworkSize=800 </span>seems
to do the trick. One needs to rebuild the graph though; by
looking at the code, it looks like it discards these
non-reachable islands at graph building time, which is exactly
what I need. Well done ! Any drawback to raising this value to
large numbers ?</div>

<div>Peter,</div>
<div>yes, I think you’ve put the finger on the problem: my
map has lots of small ways that are not connected to the
rest of the graph. So I think it actually finds an edge to
start off with, but then it can’t find a route because
it’s an island, although not a « oneway island », just an
isolated island. So is the config
prepare.minOnewayNetworkSize although useful in this case
?</div>
<div><br>
</div>
<div>In the SO issue you mention, it says that one should
try to « decrease prepare.minNetworkSize », is that
correct or do you mean actually « increase » the value ?
and then should I recompile and rebuild the graph when I
play with this value or can I just restart the server ?</div>

Maybe your start point is in a trap due to a barrier

Maybe you try <a moz-do-not-send="true"

<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>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>
