off-road, etc) has under his clothes, in "emission" mode. If the skier
is taken by an avalanche, the others members of his group turn their AT
in "search" mode and it helps finding your friend alive under the snow.
An AT is one the three basic emergency tools every backcountry skier
have. The two others is tube (to precisely search for your friend under
the snow once you have an approximate position thanks to the AT) and
shovel (to pull out your friend from the snow). </div></blockquote><div class=""><br class=""></div><div class="">1.

Reading the wiki on amenity=training, my impression is that most training=* are likely to be staffed with instructors. In my area instructors may setup temporary beacon parks or use permanent ones but for individual practice the beacon parks are usually unstaffed. I don’t know that this is a big deal for OSM tagging, so amenity=training, training=avalanche_beacon is probably okay.</div><div><br class=""></div><div><blockquote type="cite" class="">The second things to map with this key is avalanche transceiver
checkpoint. It is a fixed installation that detect your AT when it's on
"emission" mode and then tell you if it works well. It's most of the
time put on official resort map, as you can see it on the <a rel="nofollow" class="external text" href="https://woody.cloudly.space/app/uploads/les-deux-alpes/2020/11/2021-no2-plan-hiver-ro-bat-hd.jpg">"les deux Alpes" ski map</a>.
They are most of the time at the entrance of well-known backcountry, or
at the arrival of major lifts.

I think of a checkpoint as a staffed location or station where your passage is blocked until you provide sufficient documentation, etc. Reading the wiki, it sounds like OSM use is more general including places you can just sign a log book. In the areas I am familiar with the facility you describe would be simply a device set to receive AT signals and visually indicate when it detected one. These are usually located at the few designated areas where you are allowed to exit the groomed pistes. You ski past, single file and separated enough that each individual’s AT’s transmissions are independent, and verify that your AT is transmitting properly. There is no one there to bar your passage if your AT is not working properly. There is no receipt issued or log signed. So I am inclined to use something other than checkpoint=avalanche_transceiver though I don’t have any great suggestions and a quick look at taginfo and the wiki didn’t give me usable ideas.</div><div><br class=""><blockquote type="cite" class=""><div class="">On Oct 17, 2021, at 3:25 AM, François Bojarski via Tagging <<a href="mailto:tagging@openstreetmap.org" class="">tagging@openstreetmap.org</a>> wrote:</div><br class="Apple-interchange-newline"><div class=""><div class=""><code class="">Hello dear OSM community, </code><br class=""></div><div class=""><code class="">I made a <a href="https://wiki.openstreetmap.org/wiki/Proposed_features/Avalanche-transceiver" target="_blank" title="https://wiki.openstreetmap.org/wiki/Proposed_features/Avalanche-transceiver" rel="nofollow" class="">proposal</a> about avalanche transceiver checkpoint and training zone.
