What is a .GDB file?
The common language of GPS devices.
A GDB file from Garmin stores GPS waypoints, routes, and tracks created in MapSource or BaseCamp. Open it with the free Garmin BaseCamp (File > Import), or convert it to GPX or KML with the free GPSBabel. MapSource is discontinued, so BaseCamp or GPSBabel is the right tool on any modern PC.

Is my .GDB file uploaded anywhere?
No. Your .GDB 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.
