GPX stats helper library

This Java library provides static helper methods to read from GPX 1.1 files using the official XSD schema from TopoGrafix. The following parameters can then be calculated:

• Total distance [km]
• Ascent/descent elevation [m]
• Lowest/highest elevation [m]
• Total duration [h]
• Duration in motion [h]
• Start/end time [h]
• Max/average speed [km/h]
• Start/end position [lon, lat]
• Start/end geo-position description (using the free Nominatim API Reverse Geocoding (OpenStreetMap data))

Technical requirements:

• Java 11+

Usage:

final File file = new File(Example.class.getClassLoader().getResource("example/example1.gpx").getFile());
final GpxType gpx = GpxConverter.convertGpxFromFile(file);
final TrkType track = gpx.getTrk().get(0);

final Double totalDistance = DistanceTotalCalculator.fromTrk(track);

final ElevationDelta delta = ElevationDeltaCalculator.fromTrk(track);

final ElevationRange range = ElevationRangeCalculator.fromTrk(track);

final FirstLastWaypoint firstLastWaypoint = FirstLastWptCalculator.fromTrk(track);

final Duration totalDuration = calcDateTimeDifference(firstLast.getFirst().getTime(), firstLast.getLast().getTime());

final Long durationInMotion = DurationInMotionCalculator.fromTrk(track);

final Double maxSpeed = SpeedMaxCalculator.fromTrk(track);

final Double avgSpeed = SpeedAvgCalculator.fromTrack(track);

final GeocodeReverseModel startPos = GeocodeUtil.convertFromJson(GEOCODE_SERVICE.reverseGeocode(
    firstLast.getFirst().getLat().toString(), firstLast.getFirst().getLon().toString()));

final GeocodeReverseModel endPos = GeocodeUtil.convertFromJson(GEOCODE_SERVICE.reverseGeocode(
    firstLast.getLast().getLat().toString(), firstLast.getLast().getLon().toString()));
