<div>What about extracting routing data for a specific city? </div>
<div>I've tried using bbike <a moz-do-not-send="true"
href="http://download.bbbike.org/osm/">http://download.bbbike.org/osm/</a>
, extracted this: <a moz-do-not-send="true"

city, Lithuania) and executed ./graphopper.sh import
vilnius-city-latest.osm.pmf</div>
<div><br>
</div>
<div>Then I've downloaded Lithuania map from here <a
moz-do-not-send="true"
href="http://download.mapsforge.org/maps/europe/">http://download.mapsforge.org/maps/europe/</a>
, created folder vilnius-city-latest-gh and pasted it into
Android file system. </div>
<div><br>
</div>
<div>When I run app it displays a map but when I try calculate
distance between two points (with your methods) app crashes. </div>
<div><br>
</div>
<div>Then i've tested it with australia map and it's routing
data and it works. So I'm guessing I have some problems with
routing data that I've got from bbbike and I've no idea how
else to extract correct routing data. </div>

<div>Hi Ignas,<br>
<br>
have a look into the android/ folder. There you see how
it work. And you can set the algorithm in the GHRequest
object. If contraction hierarchy is enabled only
bidirectional algorithms will work. The GHResponse
contains all the necessary information like points and
instructions.<br>
<br>
<div>
<div class="im">> Should I first make some kind of
subgraph (due to efficiency)?<br>
<br>
</div>
There are several techniques to make it faster like
CH, but you could also use more heuristical routing
algorithms, sorting the graph, in-memory instead
memory mapped etc<br>
</div>

Peter.<br>

<div dir="ltr">Hello,
<div><br>
</div>
<div>I've got Graphhopper going on my Android
device. </div>
<div><br>
</div>
<div>Now my goal is to select two points on the
map, apply one of the algorithms (Dijksta, A*,
etc) and display results with an overlay. </div>
<div><br>
</div>
<div>Due to lack of documentation & being a
little bit in a hurry, could somebody point me
where/how to start? </div>
<div><br>
</div>
<div>I understand the basics - getting point's
coordinates, displaying an overlay with results.
The part where I'm confused is how to apply
search algorithms in Graphhopper? </div>
<div><br>
</div>
<div>Should I first make some kind of subgraph
(due to efficiency)? </div>
<div>How can I get all the points (on streets,
i.e.) between those two points?</div>
<div>Is there something like getStreet(point1,
point2) that gives you back most likely street
between your two points? </div>
<div><br>
</div>
<div>Pardon my naivety, but I'm new to mapping,
routing, etc & my BA thesis' handing in
deadline is coming really fast. ;) any help
appreciated!<br clear="all">
