Generate a .gpx-file with campings as waypoints near your track.
If you're a user of simple but sturdy GPS-devices like the Etrex 20x, enjoy being off grid or don't have a smartphone ... this tool might be interesting.
It takes a GPX-track file as input and returns a GPX-waypoints file with 'campings' near your tracks. These campings will show up as little tents on the map of your GPS (see image). When feeling tired, just zoom out a bit and ride to the nearest tent and get some sleep.
Theoretically you could use a really big waypoints file with all campings but then a lot of the GPS devices will slow down or not even load all waypoints. With this tool, you make a selection of only the campings you will get near.
After uploading your GPX-track and downloading the generated waypoints-GPX, just put both files on your device. In contrast to the GPX-track, you don't have to 'load' the waypoint file on the device. The camping waypoints will always appear.
Note that you might need to tweak some display settings. (By default, most Garmin devices hide waypoints when zooming out beyond a certain scale). For Etrex devices go to Setup -> Map -> Advanced Map Setup -> Adjust Zoom Ranges -> Zoom levels -> User Waypoints. Use a setting of at least 8km.
If you open the waypoint/camping in your device in the description you will see the phone number and/or e-mail address if available.
All campings from the Open Street Maps are used except the campings that have the tags
