Select a command to get help. Then, click apply to execute it.
If one track is selected, the command will apply only to this track.
Else the command will apply to all tracks.
Duplicate the track.
Revert the track points order.
The last point becomes the first, etc.
Only points coordinates and elevation are kept after the operation.
Create a new track by merging all tracks.
Each track will appear as a segment in the merged track.
The order of the merge is the same as in the table. Points times are kept only if all tracks
have time data and are chronologically sorted.
Merge all track segments into one segment.
All data (time, elevation, ...) is preserved.
Create a new track from each segment of the track.
Reduce the number of track points.
The result's count may be lower than requested but never higher.
Reduce the number of track points to get a file with the requested size.
The result's size may be lower than requested but never higher.
WARNING: this operation can be long.
Reduce the number of track points using the provided epsilon. This value, in m, is used in the
Douglas-Peucker polyline reduction algorithm (Wikipedia).
An higher value removes more points.
Note: The two other operations indeed compute the epsilon for you.
Replace points elevations by the MapQuest elevation data.
MyGPSFiles gets MapQuest elevation for points every 90m (or more if the track is longer
than 90km). Then it interpolates values to the other points.
Replace points elevations by the Google Earth plugin elevation data.
MyGPSFiles does not interpolate here but it gets all points elevations from the plugin.
WARNING: This operation is slow (can be several minutes). But the result is really good for
visualization on Google Earth.
Add points to the track to get a more accurate elevation profile.
For correction with MapQuest data, it creates points to have at least one point every 90 meters
in the limit of 1000 points.
With Google Earth plugin, this is one point every 30 meters with no count limit.
Set the same elevation for all points.
Increase or decrease the elevation of all points by the provided offset.
Use a negative offset to lower it.
Change the track start time (the first point time).
All points times will be updated with the same delta.
Date format: DD/MM/YYYY - Time format: hh:mm:ss or hh:mm:ss.SSS
Update points times to simulate the specified speed. Only the start time will not be modified.
Update points times according to the provided time acceleration factor.
A factor of 2.0 will change times as if the gps moved 2 times quicker. Use 0.5 for a movement 2
Only the start time will not be modified.
Cut the track into segments where it intersects the cutter segment line - the red line on the
No point is added. No point is removed. Only segments are created.
Cut the track into segments where it intersects the cutter segment line.
And add the intersection point to the created segments.
The point can be added to the segment after the intersection (downstream), or before (upstream)
Convert track into the selected format.
Keep only points location and elevation
Remove all elevation data
Remove all time data
Remove all heartbeat data
Remove all cadence data
Remove all power data
Round points elevations to meter.
Note: MyGPSFiles manages, retrieves and interpolates elevations at the centimeter accuracy
Round points times to second.
Note: MyGPSFiles manages and creates times at the millisecond accuracy level.

Fill the form or not (all fields are optional) and click on the share button.
This will upload your tracks on the MyGPSFiles server and provide you with a link for sharing.
The link is available for 30 days. Then, tracks will be removed from the server. You can delete
the share before if you want.
You can use Internet links (http://...).
You can also use tracks/points links. Specific to MyGPSFiles, they look like @T/ppp. Example:
the "@2/54" link will locate the 54th point of the 2nd track in your share.
To check how links behave, click on the preview button.
The provided links are private. Only you (and the people you share them with) can know it.
