[GraphHopper] GraphHopper Digest, Vol 41, Issue 6

[Razvan C]

For Geocoding I think you can take a look to                  Nominatim                  tool (http://wiki.openstreetmap.org/wiki/Nominatim).

You cannot use nominatim if you want offline geocoding. This    would mean to port nominatim to android is impossible. If you want    online geocoding then offline routing is senseless too IMO. 

But using a graphhopper webservice from Android is easy: have a look    into the web project and copy & paste GraphHopperWeb to your    project and use it instead of 'GraphHopper.java'. Then, to use    nominatim, you can use NominatimGeocoder
 
If you want to make an offline GPS you will need a nominatim option, because requesting a user to tap on map for getting a route is not so right.
Why is impossible to port nominatim to Android, taking in account that you don't port whole World but just a portion?

   1. Re: Speed Limits (Peter K)


 
Maxspeed (http://wiki.openstreetmap.org/wiki/Maxspeed) / Speed limits (http://wiki.openstreetmap.org/wiki/Speed_limits) are defined in OSM. 
>Again: we already parse maxspeed for cars 
>
>How can I get maxspeed in Android?
>   
you can only get the speed which could be defined due to the
    maxspeed tag but it could be also without limit and defined via the
    highway type:

// the speed in km/h
vehicleEncoder.getSpeed(edgeIterator.flags())
