<div class="moz-cite-prefix">Hi Jaak,<br>
<br>
cool, this is really great news! As I already wanted to look into
this, but hadn't the time so far.<br>
<br>
Regarding 1) The returned value is as expected (normal) meters.
Hopefully I can digg into the code next week.<br>
<br>
Regarding 2) ghz is a zipped folder and can be opened via the
Helper.unzip<br>
<br>
> mapsforge library<br>
<br>
Oh, so the mapsforge data can be opened? Nice!<br>
<br>
Regarding 3) This will be solved in issue-17. It is the problem of
mapping from "real world gps coordinates" to graph node ids.<br>
You can partially work around this by increasing the precision of
Location2IDQuadtree index<br>
or checkout the master (not really recommended yet, as
incompatible file layout and probably other minor issues)<br>
<br>

<div><br>
<div> I just pushed a sample with Graphhopper routing to Nutiteq
3D SDK AdvancedMap3D samples: <a moz-do-not-send="true" href="https://github.com/nutiteq/hellomap3d/">https://github.com/nutiteq/hellomap3d/</a>,
see GraphhopperRouteActivity.java . Nutiteq SDK is quite
similar to Mapsforge, just with 2.5D perspective and rotation
capabilities. And with a lot of different data source Layer
implementations, from geotiff and shapefiles to mapsforge
library.</div>

<div> Issues with grasshopper:</div>
<div><br>
</div>
<div>1) major problem - all the routes in my area (Estonia) are
a bit more than 2x too short. Instead of 100 km I have 45 or
so. Could it be that it is so much north and calculations of
distances become wrong? If the "meter" is really "mercator
meter" then the value could be even right, but calculation of
mercator meters to real meters, when the route is from south
to north, is not trivial (or not possible at all). I created
test dataset for Baltics 3 countries: <a moz-do-not-send="true" href="https://dl.dropbox.com/u/3573333/baltics.ghz">https://dl.dropbox.com/u/3573333/baltics.ghz</a>
, where it is observable. </div>
<div><br>
</div>
<div>2) some minor issues. I did not figure out how to open
properly .ghz file with the API. So the sample asks now for
.map file inside <map>_gh folder, so the files must be
uncompressed in SDCARD. But it would be nicer to enable just
to open ghz file, and GH would uncompress it automatically.</div>
<div><br>
</div>
<div>3) start and endpoints are sometimes not optimal, quite far
from clicked location, and there seem to be much closer nodes
to given points. I added lines from clicked location to first
and from last location to make it nicer. Maybe some tolerance
in graph generation, or in routing?</div>

<div>Your pull requests with fixes to the demo app are very
welcome, quite possibly I just did something wrong</div>
