Command line GPX smoother written in Java.

This is a quick port of the GPX smoother from a javascript-based web application to a stand alone java application.

Currently a simple box smoothing algorithm is used. Hopefully, the Java version of the smoother will allow for quick experimentation with some more complex smoothing algorithms.

To compile and run:

javac -d bin src\io\github\brenzy\gpxsmoother\*.java
java -cp bin io.github.brenzy.gpxsmoother.GPXSmoother -i data/test.gpx -n 5

Usage:

  -i <inputFilePath.gpx>   
  -n <number of points to smooth over (odd), suggested value = 5>   
  -e <meters to shift elevation up or down>   
  -s <maximum change in slope between points>   
  -r <min change in slope between points>,<max change in slope between points>   

The smoothed file is saved to <inputFilePath_smoothed.gpx>.
