Hi,
I’m working on an extension of the routing engine. My goal is to map a gpx
track to a osm track and then extract all osm data of the resulting track.
Right now I get only the distance, speed and points of an edge, but I would
like also to know the osm tags such as surface, highway,… of each edge. Is
there already something in place which can deliver this information or do I
have to program it on my own? Can you maybe give me some hints.
example:
GPXFile gpxFile = new
GPXFile().doImport("./track-data/Garmin_150704_Seis_Konstantin.gpx");
List<GPXEntry> inputGPXEntries = gpxFile.getEntries();
MatchResult mr = mapMatching.doWork(inputGPXEntries);
// return GraphHopper edges with all associated GPX entries
List<EdgeMatch> matches = mr.getEdgeMatches();
// now do something with the edges like storing the edgeIds or doing
fetchWayGeometry etc
for(EdgeMatch match : matches) {
long flags = match.getEdgeState().getFlags();
PointList geometry = match.getEdgeState().fetchWayGeometry(3);
//System.out.println(geometry);
System.out.print("Distance: " + match.getEdgeState().getDistance() + ",
Points per edge: " + geometry.size() + ", Speed: " + encoder.getSpeed(flags) +
", Turn cost: " + encoder.getTurnCost(flags) + ", Is forward: " +
encoder.isForward(flags) + "\n");
}
Thats all the infos I found so far about an edge. Is OSM data also stored
somewhere?
All the best,
