Upload A Trail
Here, you can upload a GPX file to our trail database and it will be added immediately! Remember, this is a free, community driven project. Please do not attempt to abuse the system. All uploaded data is immediately sent to and reviewed by the website administrators. Any inappropriate content, or data discovered to be intentionally inaccurate, will be removed. For the foreseeable future, we only accept GPX files for upload, as they tend to be the most universal format.
Your GPX file must meet the following requirements:
1) Must have a ".gpx" extension
2) Must have a valid GPX schema
3) File size must be 4MB or less
4) Must only have one track (trk) or route (rte) element
5) Must have at least 10 coordinate points (or 3 for polygonal areas)
If you believe your file meets the above requirements and is still being rejected, please email the file to firstname.lastname@example.org so we can assess the issue.
Upload Your GPX File HERE
1. Try to upload tracks without exploratory detours and backtracking. Not only does this inflate the distance calculations, but it requires more storage space and may take longer to generate. If your track has a lot of extras, trim it down to the core route before uploading.
2. If your device records elevation data, ensure that it is recording as accurately as possible. For barometric altimeters, calibrate the device before starting the track. If possible, use DEM data for calibration. If your device does not record elevations, our system will automatically attempt to add them using digital elevation models from SRTM data.
3. If your GPX file contains more than one route (rte) or track (trk) element for different trails, please try to separate them into two files. At the moment, our system will only accept GPX files with one route or track element.
For more details on GPX files, HERE is a great writeup by HikingGuy, with all the information you could possibly need, and then some!
1. Track/route data is stripped from your file and stored in a database.
2. All lat/lon values are rounded to 5 decimal places.
3. All elevation values are rounded to 2 decimal places.
4. Duplicate location points are ignored, even if they have different elevation values.
5. Elevations will be added where missing using SRTM 3 arc second digital elevation model data.
6. We don't use any track smoothing yet, so whatever track/route points are present will be retained.
7. Creator, name, description, etc... are ignored. Only track/route data is utilized.
