[GraphHopper] Drawing map and route

[Nicolas Gillet]

Hi Dmitriy

GraphHopper only meant to compute routes between two points, displaying it on a map is a hole other story.
However, GraphHopper come with a nice web application that can create and display routes on a map. This is the graphhopper-web module.
Here is how to use it https://github.com/graphhopper/graphhopper/tree/master/web

For desktop application you have to create your own and the hardest part will probably be to display a map background.
This can be done by either getting this map from internet through a API’s like OSM, MapQuest, Google and some other or creating your own map from data with a map rendering tool like Mapnik, the latest requiring more effort.

Hello!
Tell me please, how to start desktop application with a rendered map?

I work at eclipse, and i have four projects imports from https://github.com/graphhopper/graphhopper:
1)graphhopper
2)graphhopper-parrent
3)graphhopper-tools
4)graphhopper-web

In my class I do next :

 GraphHopper gh;
 private static final String ghLoc = "/home/dmitriy/graphhopper/core/target";
 private static final String testOsm = "/home/dmitriy/graphhopper/russia-european-part-latest.osm.pbf";
 gh = new GraphHopper().setInMemory(true, false).setEncodingManager(
                new EncodingManager("CAR")).setCHShortcuts(true, true).setGraphHopperLocation(
                ghLoc).setOSMFile(testOsm);
        gh.importOrLoad();
        GHResponse ph = gh.route(new GHRequest(51.2492152, 9.4317166, 51.2, 9.4).setAlgorithm("dijkstrabi"));

It works fine, but I can not understand how to run a graphical map and draw a route on it.
Would you please explain to me?
I will be very grateful!
