GPX Elevation Editor

What it does

Free online GPX editor for fixing those annoying GPS elevation spikes when your device goes crazy in tunnels or under cliffs. Visually drag elevation points back to reality, auto-detect anomalies, apply smart smoothing, and export clean GPX files. Perfect for trail websites, Strava addicts, and GPS perfectionists who hate seeing impossible 100m jumps in their data. 100% browser-based, zero uploads, your data stays private. Built by a hiker tired of publishing wrong elevation stats.

  I'm working on a GPS track visualizer for quite some time. It shines in hilly and mountaineous terrain (where a 3D view makes more sense), but it also offers quite a lot of Strava-like features (statistics etc.). You can upload your GPX and FIT files manually, or sync directly with Garmin, Coros and Polar. See https://cubetrek.com for the live app and check out some examples there. It's free and opens source. Also, anyone who likes to work with 3D visualizations (especially Babylon.js), let me know if you like to help polish this thing further.

  I made a web app to generate 3D models of real places on earth from land cover and elevation data. Click anywhere on the map to get a polygon, and then click "generate". It should work at most scales, but if your watershed or region selection is too large, the result can be less exciting because it's so flat. As a warning, the 3D models can sometimes be too much for my phone. It's nicer on desktop. I'm still working better on mobile support. The land cover data I'm using gives a cool effect, but at some point I'd like to add in global imagery and clouds. The backend is a Python thread…
