The route can be distorted
Position jumps and stationary drift can add false detours or movement that never happened.
Better tracks. More trustworthy data.
Fix your GPX tracks.
Built for hikers who care about trustworthy GPX tracks.
GPXFixr helps you quickly repair your recorded track - bad points, false movement, unreliable elevation, so your track better reflects the route you really travelled. Because a shared GPX file should represent the trail - not GPS errors.
Currently focused on hiking tracks. More activity types are planned.
The problem
A recorded GPX track is not automatically a correct one.
A phone, watch or handheld GPS only records what its sensors estimate at that moment. Weak reception, signal reflections, pauses, dense point sampling and poor altitude data can all leave errors behind.
Distance can be exaggerated
Small location errors accumulate, making the track longer than the route actually travelled.
Elevation and ascent can mislead
Noisy altitude values can produce an unrealistic profile and an inflated total ascent.
Why I built GPXFixr
Shared GPX tracks should describe the real route.
I kept seeing GPX tracks shared online that contained GPS errors - tracks with incorrect distances, inflated ascent, noisy elevation profiles and routes that didn't quite follow the trail.
Thousands of these recordings are uploaded to hiking websites and reused by other people for planning, navigation and route comparison. When those files are "dirty", their geometry, distance, elevation and calculated ascent may not be dependable.
GPXFixr exists to make those shared tracks cleaner and easier to trust before they are archived or shared.
What it does today
A fast, visual way to repair common GPX problems.
Upload a file, inspect it on the map and elevation profile, apply repairs, compare the result with the original and export the cleaned track.
Clean suspicious points
Reduce spikes, stationary jitter and unnecessarily dense point clusters.
Repair elevation data
Replace unreliable recorded altitude with terrain elevation where appropriate.
Compare before and after
Review maps, profiles and track metrics before downloading the corrected GPX file.
Still growing
GPXFixr is a work in progress, not a finished list of fixes.
The current priority is improving hiking GPX tracks and expanding the set of recording problems that can be detected and repaired. Later, the same approach can be adapted to other types of movement, including cycling, driving and flying, where a “correct” track follows different rules.
