What file types can I upload to LogTRC?

LogTRC accepts compatible CSV, GPX, JSON, LOG and BIN ride logs, including VESC Tool, VESC Express, METR and BREmote style logs where supported.

Can I remove private sections before saving a log?

Yes. Browser uploads can show a review step with a map and timeline. Add one or more cuts before saving to remove private locations, failed starts or unwanted end sections.

How does LogTRC handle GPS teleports?

When GPS teleports are detected, the track page can enable a GPS teleport filter to hide impossible jumps and speed spikes while still allowing the original GPS data to be inspected.

How to use LogTRC

Record a ride, upload the log, optionally trim private or unwanted parts, then open the generated track page.

1. Record a log

Use the LogTRC app, VESC Tool, VESC Express, BREmote or another compatible logger. For best GPS results, wait until the phone or GPS puck has a good fix before riding.

2. Upload the file

Open the Upload page and choose your log file. LogTRC accepts compatible CSV, GPX, JSON, LOG and BIN files.

Uploads from the LogTRC app continue directly to the normal track result. Browser uploads may show an optional review step first.

3. Review before saving

If the uploaded file can be edited, LogTRC shows a map and timeline before the log is published. You can simply press Save log to keep the full ride.

To remove a section, drag the timeline handles until the orange track is the part you want to delete, then press Add cut. You can add more than one cut before saving.

For long rides, use Zoom + on the timeline to select a smaller time window more accurately. Zoom - widens the view again, and Fit returns to the full ride.

4. Save the private delete link

After a browser upload is saved, LogTRC shows a private delete link one time on the owner page. Save this link if you want to delete the track later.

The delete link opens a confirmation page before anything is removed. Anyone with the link can delete that track, so keep it private.

5. Open the track page

The track page shows the route, ride highlights, top stats, two selectable graphs and a ride report. The map track is coloured by speed when GPS data is available.

Graph fields

The graph dropdowns only show numeric fields that are actually populated in the log. Empty or all-zero fields are hidden.

You can drag over the graph to zoom, use the mouse wheel to zoom, and hold Shift to pan. Use Reset zoom to return to the full graph.

GPS cleanup

Some logs contain GPS teleports: sudden jumps that can create impossible speeds or long straight lines on the map. When LogTRC detects them, the track page can show a Filter GPS teleports option.

The filter is enabled by default when teleports are detected. You can switch it off on the track page if you want to inspect the original GPS data.

Supported log types

CSV: VESC/ESC telemetry and GPS fields when present.
GPX: GPS tracks for map and route viewing.
JSON: compatible telemetry exports, including editable METR-style series where possible.
LOG/BIN: BREmote-style binary logs with GPS/VESC telemetry where supported.

Tips

Keep the phone or GPS puck with a clear sky view.
Use GPS speed, for example gnss_gVel, for true riding speed.
Use VESC speed as a separate board/motor calculated value.
Use the upload cut editor to remove your home location, a failed start, or an unwanted end section before publishing.
If a graph field is missing, it was probably empty or all zero in the CSV.
For accurate Wh/km, make sure the log contains energy-used data such as watt_hours_used.
