Field notes
The page says terrain comes from the USGS 3D Elevation Program and describes drawing routes over that terrain before previewing them in a ride simulator. It also offers a field handoff: print a build sheet or send a GPX to a phone GPS app, then stake the route on the ground. Projects are saved in the same browser on the same computer, and the tool is not built for phones.
