What is a .OSM file?
The common language of GPS devices.
An OSM file is raw OpenStreetMap geographic data, points, lines, and areas with tags, stored as plain XML. Open it in JOSM or QGIS to see it on a map. For large regional extracts, use the .osm.pbf version instead; raw XML for a whole country runs into many gigabytes.

Is my .OSM file uploaded anywhere?
No. Your .OSM file is read by your browser and never sent to us. Only the background map tiles are loaded from OpenStreetMap, which sees which map area you're looking at, not your data.
How is the elevation gain calculated?
We add up every climb between track points, ignoring tiny wiggles of less than 3 metres that come from GPS noise. That's close to what Strava and Garmin report; barometric devices may differ slightly.
How do I open a Shapefile?
A Shapefile is several files. Drop the whole .zip, or select the .shp, .dbf and .prj files together. With only the .shp you'll see the shapes but no attributes.
Can I convert GPX to KML or GeoJSON?
Use Export GeoJSON to save everything you see. GPX ↔ KML conversion is part of our upcoming converter.
My CSV has coordinates. Will it work?
Yes, if it has columns named like lat/latitude/y and lon/lng/longitude/x. Every row becomes a point with the other columns as properties.
