Hi, I am trying to map-match gps data from high accuracy GPS RTK, and I obtain the following error : No edge matches found for path. Too short? Sequence size 1288 java.lang.IllegalStateException: No edge matches found for path. Too short? Sequence size 1288 at com.graphhopper.matching.MapMatching.computeMatchedEdges(MapMatching.java:367) at com.graphhopper.matching.MapMatching.computeMatchResult(MapMatching.java:327) at com.graphhopper.matching.MapMatching.doWork(MapMatching.java:189) at com.graphhopper.matching.MapMatchingMain.start(MapMatchingMain.java:111) at com.graphhopper.matching.MapMatchingMain.main(MapMatchingMain.java:44) I have tried with 1m and 10m subsampled gps file with the same result. If you want to try, I have uploaded the file on drive :

You will need the map upper-normandy : http://download.geofabrik.de/europe/france/haute-normandie.html

Many thank for future help. regards Pierre
