Ros + openstreetmap (osm cartography package)

edit

Hi,

Is anyone knows how to work with ROS and Open Street Map ? I have ROS indigo.

The package is here: http://wiki.ros.org/osm_cartography

I would like to have something like on this picture:

My code for now is the following but doesn't work:

int main(int argc, char **argv)
{

ros::init(argc, argv, "osm");
ros::NodeHandle n;
ros::ServiceClient client = n.serviceClient<geographic_msgs::GetGeographicMap>("geographic_msgs");
geographic_msgs::GetGeographicMap srv;

srv.request.url = "package://home/user/map.osm";
if(client.call(srv))
{
     ROS_INFO("connected");
}
else
{
     ROS_ERROR("failed");

}

return 0;

}

Thanks you so much in advance.
