GPXConv

GPX track converter: post-process routes and tracks typically produced by GPS loggers.

• Reads from file(s) given as argument (or STDIN) and writes to STDOUT or a file.
• Can append segments from multiple tracks and files (sequential composition), using the metadata of the first track.
• Can complete gaps in input file(s) by merging data from an alternative GPX file (parallel composition).
• Concatenates all given tracks (or routes) preserving segments, collecting waypoints.
• The metadata (header) of the first input track is used for the output track.
• Reports missing data and by default ignores points containing implausible data.
• Optionally filters out points before or after given time limits.
• Optionally filters out points with an element value below or above given limits.
• Optionally prunes comments, extensions, or extension elements with value below or above given limits.
• By default carries over missing altitude and time data between segments.
• By default fills in missing altitude and time data by interpolation within segments.
• Optionally inserts interpolated points in long gaps (default 1800 seconds sufficient for exiftool).
• Optionally corrects elevation and and smoothens tracks. (Orthometric height = GPS ellipsoidal height - geoid height, see http://www.unavco.org/edu_outreach/tutorial/geoidcorr.html)
• Produces statistics including ascent/descent rates, optionally also for climbing phases.
• Optionally produces additional statistics on a per-segment or per-day basis.
• Optionally calculates approx. total energy spent by biking along the resulting track.
• Prints information (if enabled), any warnings (if enabled), and errors to STDERR.

Usage:
