Overlay waypoints imported from an GPX can be added to the route quite easyly in app and on website - also in app they are “tapable”, thanks to @devemux86 :
There are several mountain pass databases available already, but I was interested in the mountain passes from OSM database (they are shown in app and on website, but in app they are not “tapable”).
It is quite easy to export mountain passes e.g. from overpass turbo, but there you get also a lot of them you might not be interested in (e.g. them in paths, steps, footways, cycleways or even in tracks).
So I set up a web page where you can show / hide OSM passes by category of ways where they are in, select / deselect rectangle areas and download them as GPX:
- Select wanted highway types on the left panel (see link to explanation of OSM highway types at top of left panel)
- Zoom map to your desired area
- Select / deselect passes with buttons / radiobuttons on right panel
- Save your selection with button at bottom of right panel
Some technical background information:
To reduce the load on overpass api, once a week (in the night from sunday to monday) the information about mountain passes and their parent ways is requested from overpass api and stored on gpxshaping.de. Additionally I set the browser cache duration of data files to one week - so the downloaded information can be up to two weeks old.
Furthermore the test depth is low - there might be bugs in, feedback is welcome!
