I am trying to write a python program for personal use that takes in 2 GPX files and matches segments and tells if one of the gpx files is trailing the other. For example, if two runners ran on the same trail within 100 meters apart for some section of the trail the program would be able to return how long the where within the specified distance of each other.

At the moment I have parsed the file using gpxpy.

`openGpxFile = open(fileName, 'r')

parsedGpxFile = gpxpy.parse(openGpxFile)

track1 = parsedGpxFile.tracks[0].segments[0].points`

And then put the data from each track into an array with the following loop

cords = []

points = 0

for point in track: 

    cord = [point.longitude, point.latitude, point.time]

    cords.append(cord)

My next steps in theory would be to

• Buffer that lat and long coordinates to adjust for jitteriness (not sure best way to do this)


• Find overlapping segments (not sure how to do this)


• If there are overlapping segments, line up the tracks by time stamps for the given region and calculate distance apart from a point on track1 to the point with the corresponding on track2 (not sure how to do this either)

Not sure if this idea is effective, and if it is how any of the steps can be implemented and what libraries would be good to use.
