OpenStreetMap
Hi. During my engagement in swedish hiking groups I became aware of the need for a service for extracting GPX-files with huts and shelters to put into GPS-devices and phones.
I built a simple website to fill this need which was a fun and learning experience :)

I believe one of your example queries does not return any geometry information for ways, i.e. you’re probably missing out a few thousand objects. Maybe try this one here: https://overpass-turbo.eu/s/QHD

Hi mmd, which query do you mean?
This is the function that builds the query: function buildQuery(areaCode) { var q = ‘https://overpass-api.de/api/interpreter?data=[out:xml][timeout:325];area(‘+areaCode+’)->.searchArea;’+query+’out;’;
I decided not to add “center” after out because it does not seem to be necessary and make the query time much longer. togpx() handles the data like this: “Points are converted to Waypoints. Lines are converted to Tracks. (Multi)Polygons are represented as a Track of their outline(s).” see https://github.com/tyrasd/togpx
I don’t know how this looks on a GPS-device because I don’t own one.

Query was the second one “huts, shelters, shalets, … “. In your query you use “nwr” which returns nodes, ways, and relations. However, for the ways, you only receive the “node ids”, not the actual nodes with lat/lon details.
togpx cannot create anything meaningful in this case, as there’s simply no geoemtry available. Please compare:

When I search for “Brittany”, it finds Q327, which is the historical entity and has no OSM relation ID, as it doesn’t exists anymore.
The correct result would be Q12130 which has the correct relation ID.

Otherwise it worked quite well with area “ Sweden “, with Firefox mobile 68.5.0 and osmand.

Hi Hamlet. Have a look on WP:Brittany. It says: “This article is about the cultural region in the north-west of France. For the current French administrative region, see Brittany (administrative region).”
So in this case “Brittany (administrative region)” should work in your case as it is linked with Q12130.

@mmd Thank you! Now I understand. I will add center to all queries then. :)

Right, it’s a bit cumbersome, but it works ! :-)
You might want to add some kind of completion, looking for wikidata items with OSM IDs, because when I tried, your tool asked me to change the first item, which was confusing.
Anyway thanks for your tool. You could add a “water” section, I like to have drinking_water, toilets and such highlighted on my maps.
Regards.

I now added jQuery Autocomplete from the Wikipedia API. I’m quite happy with the result! :)
