[City on Foot](https://cityonfoot.me/) GPX viewer

# GPX viewer

Open a walk recorded by your phone, watch or a route planner. See the route line, how far and how high you went, your moving time and a split for every kilometre or mile.

## How to use it

Export the walk as GPX from your app (most have a share or export option), then drop the file above or choose it. Tracks, track segments, planned routes and waypoints are all read. Switch between km and miles for the splits.

## How this is worked out

Distance adds up the great-circle (haversine) distance between points on a sphere of the Earth's mean radius, 6,371 km; gaps between track segments are not counted. Elevations are averaged with their two neighbours on each side, then a climb or descent only counts once it adds up to 2 metres, so GPS jitter does not invent hills. Moving time leaves out stretches slower than about 1.4 km/h. All figures are estimates from your device's recording.

## Questions

**Why is the climb lower than my app says?**

Apps smooth elevation in different ways, and some add up every small wobble in the GPS height. This viewer smooths lightly and ignores changes under 2 metres, which keeps GPS noise out of the total but can also miss very small real rises.

**Why is there no map behind the route?**

Map tiles would have to be fetched from a map server, which would reveal where you walked. The route is drawn from your file alone, with a scale bar and a north arrow.

**What if my file has no times or heights?**

Planned routes often have neither. You still get the route and distance; the time, pace and climb figures are left blank instead of guessed.
